DIN 1.2842 Cold Worked Tool Steel
1: DIN 1.2842 steel introduction
DIN 1.2842 tool steel is an oil hardening tool steel which is supplied in the annealed condition and characterised by its characteristics of offering good durability. Tool steel DIN 1.2842 is with excellent wear resistance and its ability to hold a good cutting edge. 02 steel is a good quality general purpose tool steel often used where the expense of a high carbon high chromium tool steel would not be justified.
