1.2419 105CrW6 DIN SKS31 O7 Cold Working Die Steel

1 1.2419 Introduction:

O7 Cold Working Die Steel is one kinds of oil hardening cold working die steel, which consists of chromium and manganese, and has higher tungsten content than grade O1. The O7 steel has the best wear resistance among the O series steels, however, it has relatively low hardenability.

We can provide more services:

1、Hardening and tempering
2、Vacuum heat treatment
3、Polished bright surface
4、Milling bright surface

6 HEAT TREATMENT:

    • FORGING: Hot forming temperature: 1050-850oC
    • SOFT ANNEALING: Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
    • STRESS RELIEVING:Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
    • HARDENING:Harden from a temperature of 800-830oC followed by oil quenching or warm bath quenching approx. 200oC. Hardness after quenching is 63-65 HRC.
    • TEMPERING: Tempering temperature: See the data bellow.
Tempering Temperature Hardness(HRC)
100oC 64
200oC 61
300oC 58
400oC 54
500oC 49
600oC 41
650oC 30
