Description
3Cr2NiMnMo has good processability. It is mainly used for hot work molds. Among them, the application of plastic molds is the most common. Besides, the special pre-hardening treatment of the steel makes it have good hardness when it leaves the factory. It can reduce the heat treatment process in the processing and production of normal molds and improve economic benefits.
