Compax Supreme is a further improvement of Compax (see Alloy Digest TS-488, March 1988). The alloy is extremely clean with a homogeneous microstructure. Sulfur is very low. Carbon is held to the high end of the range to consistently achieve high hardness for molds with larger cross sections. This datasheet provides information on composition, physical properties, microstructure, hardness, and elasticity. It also includes information on heat treating, machining, joining, and surface treatment. Filing Code: TS-572. Producer or source: Uddeholm Corporation.
