Stainless Steel
STAINLESS STEEL 15-5PH Download
The 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.
