XM-12 precipitation hardening stainless steel 0Cr15Ni5Cu3Nb

XM-12 (S15500, 0Cr15Ni5Cu3Nb, 15-5PH) precipitation hardening steel overview:

XM-12 is a martensitic precipitation hardening stainless steel with high strength, high hardness and excellent corrosion resistance, very good transverse toughness and ductility, and high forgeability. XM-12 has similar processing properties to other precipitation hardened stainless steels. Low temperature heat treatment can achieve aging hardening in one step. This material is used for parts that require high transverse strength and toughness, such as valve parts, joints, fasteners, shafts, gears, chemical processing equipment, paper mill equipment, aircraft parts and nuclear reactor parts. In an environment below 593 ° C, XM-12 shows excellent oxidation resistance. Prolonged exposure to elevated temperatures will reduce the toughness of precipitation-hardened stainless steels. Providing an aging temperature can sometimes reduce this reduction in toughness. If the maximum temperature is at least 28 ° C lower than the aging temperature, the material can be exposed to this high temperature for a short time.
