1.2379 Tool Steel Chemical Composition

1.2379 die steel, high wear resistance and micro deformation, cold working die steel, wind hard tool steel, carbon content up to 1.5%, chromium content high, noisy 11.5%, heat treatment, hardness up to 60HRC. 1.2379 steel can be used to make large cross section, complex shape, strong impact, high resistance to cold working die steel, such as silicon steel sheet die, cold cutting scissors, trimming die, etc..
For various high precision, long-life cold work moulds, cutting tools and measuring tools.

1.2379 Tool  Steel Main Charactaristics 

(1) High hardenability and toughness.
(2) Excellent heat cracking resistance in the workplace, water-cooled.
(3) It has medium wear resistance, and its surface hardness can be improved by carburizing or nitriding process, but its hot cracking resistance should be slightly reduced.

1.2379 Tool Steel Main Charactaristics

(4) Due to low carbon content, the tempering secondary hardening ability is poor.
(5) It has the ability to resist softening at high temperature, but the hardness decreases rapidly when the service temperature is higher than 540 ºC (1000 ºF) (that is, the working temperature of the ability is 540 ºC).
(6) Small heat treatment deformation.
