Stainless Steel 15-5ph

Product Detail

Common Trade Names: 15-5, 15-5PH, UNS 15500 , XM-12 , W.Nr 1.4545

15-5pH steel alloy was designed to have greater toughness than 17-4 PH. The 15-5 alloy is martensitic in structure in the annealed condition and is further strengthened by a relatively low temperature heat treatment which precipitates a copper containing phase in the alloy. 15-5 is also referred to as XM-12 in some specifications
