1.2328, 45CrMoV7, 40Ch2GMF – description
Tool steel used for cold working die tools, stamps and drifters. It has good wear resistance.
The steel is meant to be air-hardened, which reduces the risk of deformations and cracks during the heat treatment. It has good hardenability but is susceptible to tempering, thus requires proper temperature during work.
