Production details 

Processing lines 

In addition to the extremely extensive processing of metal sheets, we 

have at our disposal various processing lines which are also extremely 

interesting for the construction of machinery and plant equipment when 

stainless steel is involved. With our high-speed eccentric and hydraulic 

presses we can produce punched, bent and embossed parts from slit 

strips precisely and quickly up to material thicknesses of 5 mm. Benefit 

from our many years of experience in the field of tool-intensive processing 

of stainless steel with follow-on tools. 

Profile bending 

machine 

Using a new ultra-modern CNC 

controlled profile bending machine 

we can repeat the bending or also 

straightening of tubular or full profiles 

with absolute accuracy. Particularly 

squared and rectangular tubing but 

also C-profiles can be quickly and 

inexpensively formed to attain the 

required radius. In the case of round 

cross-sections a tool specially adapted 

to the diameter is needed to counteract 

the risk of torsional twisting. 

Should we not have any suitable tools 

in production, these can be procured 

relatively quickly. As a rule, the most 

common round steel and tubular 

diameters are available as a tool at the 

machine manufacturer's. In the case 

of our profile bending machine we

also have special tools at our disposal 

which allow us to bend thin-walled 

angular profiles. We can bend up to 

a profile height of 300 mm. With full 

material a profile diameter of up to 

60 mm is possible and with tubes up 

to an external diameter of 114 mm. 

Surface finishing 

Important to know: 

We cover the needs of all the 

industrial branches!

Housings and containers make up our routine business. We use experienced 

welders and grinders as well as modern machines for the reworking and 

finishing of special and series components in machinery and plant construction. 

Irrespective of whether grinding, blasting or pickling, you know you 

can always rely on us to supply the perfect surface finish, particularly in the 

area of the welds.

Materials and surfaces 

Stainless steel 

History 

The first “stainless steel” was patented 

by Krupp in Essen in 1912. 

Alloys, which can be classed under 

the general heading “special steel”, 

had already been developed much 

earlier (around 1740 with crucible 

cast steel). 

Definition 

For our purposes it is important 

to remember that the steel we are 

concerned with here is not simply 

“special steel” but “stainless steel”, 

a very special subgroup. “Stainless 

steel” is characterized by particularly 

high resistance to many naturally 

occurring environmental factors 

which promote corrosion. But there 

are also certain chemical substances 

that are naturally capable of corroding 

stainless steel, such as hydrochloric 

acid or a lack of oxygen in 

the ambient atmosphere. The term 

“stainless” is therefore merely intended 

to highlight its special value. 

What is "stainless 

steel" actually made 

from? 

Its main constituent is naturally iron 

(Fe)! When describing the material, 

however, this natural element is 

normally no longer specified. Many 

material descriptions only mention 

the elements of importance for 

determining the properties of the 

alloy, e.g. Cr = chromium, Ni = 

nickel, Mo = molybdenum etc. 

What makes stainless 

steel so resistant to 

corrosion? 

Chromium (Cr) is one of the most 

important alloying elements. Present 

in proportions from about 

12 % upwards, it is needed to 

form the protective oxide layer, 

together with oxygen, on the 

surface of the steel. This process 

is known as “passivation” and may 

take several days. However, the 

process can be speeded up considerably 

with the aid of nitric acid 

(an oxidizing acid), thus reducing 

the time required to repair surface 

damage or contamination. The additional 

alloying of further metals, 

such as molybdenum (Mo), then 

enhances the corrosion resistance 

still further.

What points must be 

taken into account? 

When exposed to environments 

lacking in oxygen, stainless steel 

can corrode just like every other 

corroding steel – unless a protective 

layer has already formed. 

Welds which have not been properly 

treated with a passivating agent 

can corrode very rapidly in swampy 

or muddy waters, i.e. water containing 

little oxygen. The effects of 

heat, for instance incorrect welding 

or during heat treatment (annealing 

/ hardening), can also change 

the structure of the material in such 

a way that the stainless steel can 

corrode or even break, i.e. become 

brittle. 

What are the 

commonest 

designations? 

Numerous designations are encountered 

today, such as V4A, V2A 

or 18/10. The short designations, 

such as “V4A”, come from the 

test labs at Krupp and refer to a 

test series. The designation “A4” 

which is frequently found on screw 

parts of stainless steel is derived 

from this. The numbers 18/10 on 

many household cutlery parts, for 

example, stand for the alloying 

constituents chromium (18%) 

and nickel (10%). Such names as 

Cromargan, Remanit and Nirosta 

are internal proprietary names. All 

these examples are very general in 

nature and too imprecise to characterize 

a material. Since there are 

many types of stainless steel with 

very different properties and fields 

of application, it is important to 

always specify the material number 

for certain areas of use. 

The number “1” in front of the full 

stop stands for steel in this system. 

The number “4” after the full stop 

indicates that this is a stainless steel. 

The standard short designation 

helps to simplify identification of 

the chemical composition. In our 

example, the chemical composition 

is: X5CrNi18-10 meaning that 

this steel contains the following 

constituents: 

•X5 = carbon concentration in 

hundredths percent by 

weight (e.g.: 0.05 %) 

•Cr = chromium 

•Ni = nickel 

•18 = 18 % chromium 

•10 = 10 % nickel 

Physical properties 

Both the chemical composition of 

the material as well as a possible 

cold forming have an affect on the 

magnetizability. Stainless steel can 

react magnetically in accordance 

with these factors and also depending 

on its structural composition.

Materials and surface finishing 

Why stainless steel? 

Durablity and high resistance 

Stainless steel is frequently the material 

of first choice wherever a part is 

required to offer durability, neutrality 

and a service life spanning decades. 

Examples: wastewater and sewage 

plant engineering, in environmental 

technology for hazardous substances, 

in the foodstuffs industry, attachments 

and linings. 

Aesthetic appearance and 

design-enhancing properties 

Architects and designers have long 

since selected stainless steel as their 

“design steel”. Today design elements 

in stainless steel are featured 

in virtually all manner of consumer 

goods, structural components and 

service facilities. Indeed, it would be 

hard to imagine life without it! The 

aesthetic appeal of stainless steel can 

be described in just a few short terms: 

- brilliant and shiny 

- slender and elegant 

- robust and functional 

Ecological benefits in the 

production of stainless steel 

Compared with the competing 

material sectors, such as plastics, 

aluminium etc., the steels, and stainless 

steel in particular, are extremely 

environmentally friendly. This starts 

with the significantly better balance 

of energy and resources in the 

production process and ends with 

a more favourable recycling and 

reintroduction into the raw materials 

chain. Thus from this point of view, 

anyone deciding in favour of stainless 

steel, is taking a positive step towards 

protecting and improving the quality 

of our environment. 

High mechanical strength 

and toughness 

Not without good reason, the Construction 

Technology Institute in 

Berlin (as the supreme construction 

supervisory authority) has made 

stainless steel the No. 1 material for 

important load-bearing and attachment 

situations in the construction 

sector. Stainless steel becomes even 

stronger when formed – a process 

known as strain hardening. Despite 

this, however, stainless steel remains 

tough without breaking as a result of 

abrupt impacts. 

Examples: in dowel systems, in order 

to attach loads of 30 kN and more 

with a single dowel, in modern buildings 

as the visible, filigree supporting 

structure for complex glass roofs or 

glass facades, as bracing for the mast 

on ocean yachts in order to withstand 

the worst storms. 

These benefits resulting from the 

strength properties are now also 

asserting themselves increasingly in 

all sectors of the industry. Structural 

components are becoming more 

slimline and lightweight on account 

of this improved strength. In many 

areas there is now a great potential 

for economies. Together with the 

Stainless Steel Information Centre 

in Düsseldorf, the Federal Institute 

for Material Research in Berlin and 

various universities as well as welding, 

teaching and test institutes, we 

therefore endeavour to promote the 

introduction of new higher performing 

stainless steel grades. 

Looking to the future with 

new materials 

Example: lean-duplex 

As early as 2002, in other words 

before the onset of the major price 

increase in stainless steel, we had 

already started research work on new 

high-performance stainless steels. 

In 2006 we were able to obtain the 

Technical Approval no. Z-30.3.19 of 

the SAF2304 for all fastenings used 

in the building and construction 

industry. 

The advantages of leanduplex 

stainless steel, 

e.g. material 1.4362, over 1.4571 

(A5) or 1.4404 (A4L), can be summarized 

in the following simple descriptions: 

• Greater planning safety: significantly 

reduced alloy content in 

terms of nickel and molybdenum, 

therefore less expensive and improved 

price stability due to the 

relatively lower alloy surcharges 

• Double the basic strength, also in 

the welded state 

• Improved corrosion resistance, 

among other things, in terms of 

chloride induced stress fractures 

and pitting. 

• Reduced thermal expansion but no 

decline in 

thermal conductivity 

• Improved fatigue strength 

• Higher modulus of elasticity values 

(according to MPA tests Modersohn 

metal sheets >=200 kN) compared 

with the austenitic structure 

(according to technical approval 

only 170 kN)

Materials and surfaces 

Surface roughness measurement for sensitive surfaces – 

fast and precise determination in micrometres! 

Quick and targeted measurement 

of surface roughness plays a key 

role in industries subject to stringent 

hygiene regulations, such as medical 

technology and the food industry: 

these days there is growing recognition 

that the surface quality, and 

thus the determination of the surface 

roughness, is absolutely essential for 

establishing the corrosion resistance 

characteristics of a material. 

An extremely rough and badly 

ground surface on mat. 1.4404 can 

result in poorer corrosion resistance 

characteristics than a surface that 

is properly ground and smooth, or 

electropolished on mat. 1.4301! 

This is why, besides the material 

itself, the choice of surface is one 

of the key selection criteria when 

it comes to ensuring the correct 

corrosion resistance characteristics. 

Your surface quality check should 

include an analysis and confirmation 

of material surface roughness! 

The surface is precisely scanned 

along a length of up to 12.5 mm. 

This allows a range of average 

roughness values to be measured: 

arithmetical mean roughness Ra, 

square mean roughness Rq, mean 

peak-to-valley height Rz, etc.

Gottwald:

Quality assurance through surface roughness 

measurement 

Mobile material 

analysis 

In industry and the craft trades, 

there is growing interest in reliable 

information regarding the quality of 

materials. Lives may depend on the 

right material quality being used: 

the consequences of inadvertently 

selecting the wrong material, say 

for a facade fastening, could be 

disastrous... 

A new technology from the USA, 

developed for NASA (tried and 

tested in the Mars robot!) and using 

x-rays, now provides reliable 

data. The “Nitron” device quickly 

and precisely determines chemical 

elements in metal alloys (in the 

titanium-uranium element range) 

and supplies the relevant data at 

the touch of a button. 

Sheet metals, wires, tubes and also 

welded structures incl. the weld 

seams are tested. The standard elements 

for the test are: Ti, V, Cr, Mn, 

Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Hf, 

Ta, W, Re, Pb, Bi, Pd, Ag, Sn. 

It does not analyze any other elements 

present, such as Alu, C, P, S 

and Si. 

It goes without saying that purchasing 

such a device is extremely 

costly. We invested in this device 

for quality assurance purposes, in 

particular with regard to our incoming 

goods inspection, in order to 

establish unambiguous identification 

of the new Lean Duplex Steel. 

Then we had the idea of leasing the 

test device as a “mobile task force”. 

The temporary leasing of our device 

complete with operator offers our 

customers a low-cost alternative, 

should procurement of such a device 

not prove economically viable. 

Numerous companies across East 

Westphalia have already taken advantage 

of this simple alloy analysis 

/ positive material identification 

option, which is simple to 

order either by phone or 

e-mail. Please contact us 

for further details! 

We test materials for their alloy 

components using an X-ray 

fluorescence device.

Material analysis 

Austenitic stainless steel 

These type of stainless steel grades 

presently dominate the market 

and cover the most commonly 

used qualities, such as material no. 

1.4301 or 1.4404 and also material 

nos. 1.4539 and 1.4529 with a 

Structure of austenitic steel 

higher alloy content. Characteristic 

of this steel is the high content of 

austenite-forming substances, in 

particular nickel. 

Further alloy elements are chromium, 

molybdenum as well as sometimes 

copper, titanium, niobium and 

nitrogen. Adding nitrogen increases 

the steel's stretch resistance. The application 

areas for austenitic steel are 

extremely varied. This type of steel is 

used in the chemical industry as well 

as the foodstuffs industry. 

Moreover, molybdenum-free steel 

performs well within the high temperature 

range, which explains why 

it is frequently used in the construction 

of furnaces and heat exchangers. 

Its high resistance to impact at 

low temperatures is taken advantage 

of, for example, in producing containers 

for deep-frozen fluids. 

In the lower alloy range (e.g. 1.4301 

or 1.4404) austenitic steel is rela- 

tively susceptible to stress corrosion 

cracking, in particular chloride and 

hydrogen-induced versions. 

Hardening by means of heat 

treatment is not possible. It is normally 

supplied in a lumenized state 

(quenched and tempered), is soft 

and therefore highly formable. Its 

strength can be improved with cold 

forming. That's why some grades 

are supplied cold-drawn (coldstretched) 

or hard-rolled. 

With the austenitic steel grades 

the modulus of elasticity is subject 

to major fluctuations due to the 

increased strain hardening tendency. 

That's why for attachment 

systems in the construction sector 

the German Institute for Construction 

Engineering in Berlin (DIBT) 

has reduced the value from 200 to 

170 kN/mm². Tests have shown that 

major strain hardening reduces the 

modulus of elasticity. In terms of 

the structure, high strength values 

achieved through strain hardening 

may not be applied to welded constructions. 

In such a case, the yield 

point value Rp0.2 must be based on 

the strength of the metal in the annealed 

state (green strength). Refer 

to the latest version of the General 

Technical Approval Z-30.3-6, “Products, 

Connectors and Structural 

Components in Stainless Steel”. 

As a rule, austenitic steel grades are 

not magnetic in the annealed state. 

However, this can change due to 

cold forming and the martensite 

formation associated with it. In such 

a case a magnet will also adhere to 

the metal sheet or profile in the 

strain hardened area. For example, 

it is frequently the case that this 

causes die-cut washers to be slightly 

magnetic.The worldwide market for 

the austenitic steel grades and their 

fields of application are presently in 

stark decline due to the relatively 

expensive alloy content Ni=nickel 

und Mo=molybdenum.Other types, 

e.g. ferritic steel grades and stainless 

steel duplex grades, have caught up 

significantly in terms of their technical 

possibilities, and are in some instances 

considerably less expensive. 

We will be happy to advise you. 

Ferritic stainless steel 

This steel is always ferritic regardless 

of the temperature. This is achieved 

through a reduced number of 

austenite-forming elements (primarily 

nickel) combined with a high 

degree of ferrite-formers (mainly 

chromium). 

Structure of ferritic steel 

The older qualities, such as material 

no. 1.4016, were mainly used for 

household articles and in application 

areas where the demand for 

corrosion-resistance was not particularly 

high. The current ferritic stainless 

steel grades, such as material 

no. 1.4521 with an extremely low 

carbon and nitrogen content is pref-

erably used where there is a risk of 

stress corrosion cracking. However, 

as regards the surface quality ferritic 

steels show a greater susceptibility 

to wear! Roughing up the surface, 

e.g. through blasting or grinding, 

leads to a significant reduction in 

the corrosion resistance. 

Ferritic steel has a slightly higher 

yield point = Rp 0.2 than austenitic 

steel, but has a reduced tensile 

strength which somewhat limits its 

cold forming potential. E.g. deepdrawing 

and hydroforming are not 

possible in the majority of cases. A 

further characteristic that distinguishes 

ferritic steel from austenitic 

steel is the reduced strain hardening 

tendency. Thus, the ferritic steel 

grades prove interesting particularly 

on account of their high modulus of 

elasticity values (220 kN/ mm²) - see 

the comparison table on page 16. 

The ferritic steel grades exhibit a 

better fatigue strength and significantly 

lower thermal expansion than 

their austenitic counterparts. 

Martensitic stainless steel 

Martensitic steel types boast the 

highest strength but have the lowest 

corrosion resistance of all the 

stainless steel grades. Martensitic 

steel with a high carbon content is 

used for making tools and is easily 

hardened. On account of their high 

strength and relatively limited resistance 

to corrosion, they are suited to 

applications in which the material 

is exposed to corrosive attack and 

wear simultaneously. Knife blades 

are a good example of this. 

Structure of martensitic steel 

Austenitic-ferritic stainless 

steel (stainless duplex 

structure) 

In terms of structure and the alloy 

content, this group of steels represents 

a mixture of the ferritic and 

austenitic steel grades. The main distinguishing 

feature is the significantly 

higher green strength (see yield 

point Rp0.2 on page 16). For this 

reason, these steel grades are frequently 

used for producing dynamically 

stressed machine parts, e.g. 

draw-off rollers for paper machines. 

New application areas are emerging 

in the oil, gas and petrochemical 

sector where steel grades suitable 

for saltwater-proof plants and the 

offshore industry are called for. 

These steels are normally referred to 

as duplex steels relating to these two 

phases in their structure, whereby 

the combined term “duplex stainless 

steel” is more fitting since there 

are also coated metal sheets and 

sandwich metal sheets that go under 

the same name. With the commercially 

available material grades in 

the duplex stainless steel sector, e.g. 

1.4362 or 1.4462, the benefits of 

both are unified (austenitic-ferritic). 

Over the last few years, the lean duplex 

stainless steel sector in particular 

has undergone significant further 

development. Here we are referring 

to duplex stainless steel with considerably 

reduced nickel and molybdenum 

constituents, or lacking these 

entirely (e.g. 1.4062, 1.4162 or 

1.4362) in relation to the standard 

duplex stainless steel 1.4462. This 

makes these lean duplex stainless 

steel grades relatively inexpensive 

despite their high performance - see 

the example on page 17, paragraph 

5.But duplex stainless steel grade 

which a high alloy content are also 

available on the market. E.g. the superduplex 

stainless steel or now just 

recently also the hyperduplex stainless 

steel, which in many aspects are 

even technically superior to the fully 

austenitic grades, e.g. 1.4529. 

Structure of stainless duplex 

The future looks exciting and is set 

to belong to the materials made 

up of several basic structural types 

because already now the first 

triplex-stainless steel grades are being 

developed, in other words steel 

combining the three structural types 

(austenitic, ferritic, martensitic). 

Also alloys combining Cr, Ni with 

aluminium (Al) have already been 

extensively tested. These alloys with 

an aluminium content of approx.14 

% are some 10 % lighter than the 

known steel grades and capable of 

being cold-formed while demonstrating 

a high basic strength.

* New materials, provisional column values / factory data 

*1 Values in brackets in compliance with the General Technical Approval 

of the DIBt "Products, Connectors and Building Components of Noncorroding 

Steel" dd. 20 April 2009. The lowering of the modulus of 

elasticity values compared to factory and European standard values 

is based on experiments performed in the run-up to the granting of 

approval. During these tests it was established that the high tendency 

of austenitic materials towards strain hardening can cause extreme 

fluctuations in the modulus of elasticity values. The greater the level 

of strain hardening, the greater the reduction in rigidity of the material 

due to the change in the texture of the microstructure. 

*2 Values for sustained exposure to max. temperature. 

The strength values, in particular those of 

the austenitic steel grades, decline considerably 

as the temperature rises. The advantage of the 

austenitic steel grades is their continued high 

degree of strength even when exposed to high 

temperatures. Please check the values for the 

yield point and modulas of elasticity in the 

material data sheets. While Duplex stainless 

steel containing molybdenum actually becomes 

stronger when exposed to higher temperatures 

(high temperature strength), it tends to become 

Max. recommended 

operating temperature 

in air up to °C *2 

(permanent exposure) 

brittle at temperatures exceeding 300°C. This is due 

to the so called “475°C embrittlement”. There are 

examples where heat exchangers have functioned 

perfectly for many years even at temperatures of 

350°C, but also individual cases where after approx. 

30 – 40000h and temperatures exceeding 

250°C significant brittleness in the weld joints has 

been reported (source: Brücken 1997). 

In terms of the recommended maximum operation 

temperature the new Lean Duplex Steels without 

molybdenum perform considerably better.
