0CR15NI5CU3NB precipitation hardened stainless steel

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

0Cr15Ni5Cu3Nb 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. The processing performance of 0Cr15Ni5Cu3Nb is similar to that of 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, 0Cr15Ni5Cu3Nb 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.
