Rarely know fact of stainless steel

Rarely know fact of
stainless steel
Summary
Stainless steel know as iron steel and inox is a combination of metals with 10.5
percentage of chromium content in it.
Stainless steel is prominent for its corrosion resistance.
It does not easily oxidize, rust or stains with water an any other steel does.
A common use of stainless steel is for cutlery such as knives, forks and spoons

Which is chemical
composition of
stainless steel
• Stainless steel is
accessible in a wide range
of alloy that includes
different element; however
the basic element are iron,
carbon and chromium
• Low-carbon steel with no
less than 12 percent
chromium form an even layer
of oxide on its surface and is
stainless

• Other element such as nickel and molybdenum are added to improve corrosion
resistance and chromium is the deciding factor.
• Titanium, for instance, adds significant quality to the finishes items without addin
excessive weight. Nickel and niobium are helpful agents to the chromium in
resisting corrosion particularly in low-oxygen conditions.
• Properties of stainless steel.
• The amount of oxidation resistance is high when exposed to air.
• Stainless steel is relatively poor conductor of electricity.
• Basically stainless steel is ductile in nature.
• The chromium present in stainless steel form a protective layer and thus
stainless steel withstands damage caused by oxidation which is why it is
corrosion resistant.
• When compared with gentle steel, stainless steels have highly
stretchable.
• Different kinds of stainless steel.

Austenitic
Steels
• Austenitic stainless steel contains 16% of chromium and
6 % of nickel
• By including component, for example : Titanium and Copper ,
the characteristics of the steel can be changed.
• These changes can make the steel applicable in high
temperature or increase the resisteance level.
• Most steel weaken at low temperatures however the Nickel
in austenitic stainless steel which makes it suited to low
temperature or cryogenic applications.
• Austenitic steels are non-magnetic.
• These types of stainless steel quickly work-solidify, they are the
most promptly of the stainless steels

Ferritic
stainless steels
contain just
chromium as a
chief alloying
component.
Ferritic
The amount of
chromium show
ranges from 10.5
percent to 18
percentt.
Ferritic stainless
steel can’t be
solidified as a part of
the tempered
condition.
They are know
for their
resistance and
weak
fabrication
characteristics
Fabrication
can be
enhanced by
composite
changes.

Ferritic stainless steels are typically used
Vehicle exhausts
Fuel lines
Cooking utensils
Architectural trim
Domestic appliances

Martensitic
• This type of steel contains high carbon and lower chromium content.
• These features distinguish martens tic stainless steels from ferritic
stainless.
• Martens tic are magnetic in nature, and are moderately corrosive and poor
welding capability.
• They are typically used for knife blades and surgical instruments.
These are not corrosion resistant but are extremely machine-able in
nature.
• Industrial application of stainless steel. Stainless steel is used for buildings
and also for artistic purposes.
• During deco period stainless steel was is trend. Chrysler is the most famous
example.
