Material Notes:
CRUCIBLE CPM Nu-Die EZ is a new, patented die and mold steel designed for service as die casting dies and plastic injection molds. It is supplied in the prehardened condition, and is easily machined using conventional chip-making methods.This unique die and mold steel provides:Freedom from Distortion in Heat TreatmentFreedom from Worry over Heat Treatment QualityFreedom from EDM DamageCPM Nu-Die EZ is based upon the chemical composition of AISI H13 hot work steel to which sulfur has been added to provide machinability in the prehardened condition. It is manufactured by the Crucible Particle Metallurgy (CPM) Process which permits the addition of sulfur without detrimental effects on tool performance. Unlike the sulfides which form in conventionally-produced, resulfurized H13, the sulfides in this steel are small and uniformly distributed.Information provided by Crucible Industries
