1.2738, 40CRMNNIMO8-6-4, AISI P20+NI, 40CMND8 - PLASTIC MOULD STEEL, DATA ACCORDING TO ISO 4957:2001

1.2738 is a plastic mould tool steel, used mainly for plastic injection die moulds. It can be viewed as enhanced version of 1.2311 alloy, with 1% nickel content having a positive effect on hardenability.The steel is machinable, polishable, and suitable for texturing. Welding is somewhat difficult, but possible. Make sure to pre-heat and perform tempering, when the piece colled down after welding.
