Principal Feature:
Cr12 Cold Work Tool Steel is an oil hardening, high carbon/chromium type tool steel.
It has high hardness and wear resistance.
Typical Application:
Cr12 Cold Work Die Steel can achieve high hardness and good cutting performance after proper heat treatment, so it is usually used in the manufacture of cutting tools, cold dies and stamping dies.1.2080 steel has excellent wear resistance and can be used under high stress and heavy load conditions.
Heat Treatment:
Forge: Preheat at 900℃-950℃ and then raise to 1050℃-1100℃
Annealing: At 800℃-840℃ Cool slowly in furnace
Stress Relieving: Heat to 650℃, holding for one hour at heat, followed by air cooling
Hardening: Harden from a temperature of 940℃-980℃ followed by oil quenching or warm bath approx. 400℃.
