1.2379 (X153CrMoV12)
It is a high-alloy cold work tool steel with high wear resistance and high strength due to its large and hard carbides. 1.2379 is supplied in a soft annealed state (~250 HBW). Due to its high alloying elements, the material can easily harden and can reach a hardness of 60-62 HRC after heat treatment. 1.2379 is also suitable for surface treatments like PVD/CVD.
