Beginning with the lock-forming (basic quality) quality
for simple forming, through drawing and deep-drawing
quality to the extra and special deep-drawing qualities.
Each grade is defined by graduated maximum values
of yield strength and by minimum values of elongation.
The properties are determined by the melt analyses
which vary within narrow ranges. The steel for the extra
deep-drawing and special deep-drawing qualities is
decarburized by vacuum treatment and stabilized with
microalloy elements (Ti, Nb, V). These grades are
resistant to ageing.
After the basic quality for simple forming (bending,
lock-forming), the Bg grade is suitable for drawing and
stamping, but mainly for the production of welded
pipes. The C and D grades can be used for difficult
deep-drawing components, whereby the formability
increases from C to D.
The special mill quality has very good deep-drawing
properties and is resistant to temperatures up to
800° C. Because it also has an increased high-temperature
yield point, it is suitable for automobile exhaust
systems, combustion housings and for components in
heat exchangers over which fuel gas flows.
Graduated minimum values for yield strength, tensile
strength and elongation. Main field of use is the building
industry.
1) The values apply to the 0.2 % proof strength (Rp0.2 ), if the yield strength is not pronounced. If the yield strength is pronounced, they apply in the case
of general-purpose structural steels to the upper yield strength R . eL
2) This value applies only to temper-rolled products (surface types B and C).
