Impax Supreme eng-110401/1109 - Uddeholm
Hardness 325 HB.Heat treatment Uddeholm Impax Supreme is intended for use in the hardened and tempered condition,i.e.the delivery condition.When,however,the steel is to be heat treated to a higher hardness or case hardened,the following instructions may be helpful.Soft annealing Protect the steel and heat through to 700°C (1300°F).
The impressive result is the patented plastic mould steel THRUHARD SUPREME&(EP 1 251 187),which offers improved hardening through to the core thanks to the adapted compo-sition.This steel grade also has a higher toughness and polish- ability than 1.2311 and 1.2738.These properties make THRUHARD SUPREME&the ideal steel for practically all
