15-5 PH Stainless Steel

15-5 PH is a martensitic precipitation-hardening stainless steel that provides high strength, good corrosion resistance, good mechanical properties at temperatures up to 600 F degree(316 C degree) and good toughness in both the longitudinal and transverse directions in both base metal and welds. Short-time, low-temperature heat treatments minimize distortion and scaling.

15-5 PH alloy was designed to have greater toughness than 17-4 PH. The 15-5 PH 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 PH is also referred to as XM-12 in some specifications.
