Product Description

DIN 1.2008 Cold Working Tool Steel



Ningshing Special-Steel is the leading ditribution and stockist of DIN 1.2008 Cold Work Steel. Our large stock of DIN 1.2008 Cold Work Steel can meet your demand with immediate delivery. The stock involves different size range of hot rolled /forged rounds and flats, forged blocks. Delivery condiion in Annealed or Q+T.

DIN 1.2008 Cold Work Tool Steel is a low alloyed, high-carbon steel commonly used for manufacture of rasps, files and, more broadly all sharp tools requiring strength, reliability and hardness. It very high carbon content(1.3%) allows it to reach high harnesses, which are essential for this type of highly stressed tooling.

Applications
This alloy is carbon steel for the manufacture of straight razors, knife blades and hand tools.

Heat Treatment
Annealing
720 to 760 °C
Cool slowly in furnace. This will produce a maximum Brinell hardness of 220 HB.


Stress Relief
Stress relieving to remove maching stresses should be carried out by heating to approx. 650°C.
Holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Quenching
770 to 810 °C
followed by water or oil quenching
Hardness: Min.66 HRC.

Tempering
150 to 200 °C
Average hardness after tempering is 60-65 HRC.
