About Alloy 15-5

Alloy 15-5 was designed to have high strength with superior toughness than 17-4 PH. Alloy 15-5 is martensitic in structure in the annealed condition (ferrite free) and it is further strengthened by a relatively low temperature heat treatment which precipitates a copper containing phase in the alloy. Alloy 15-5 is also referred to as XM-12 in some specifications.
