Introduction
D2 steel (otherwise X155 CrVMo 12 or the same as 1.2379) is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening. D2 steel’s high chromium content gives it mild corrosion resisting properties in the hardened condition.
Typical applications
Typical applications for D2 Steel:
- Stamping or Forming Dies
