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.

FAQs & Resources

High strength alloys usually refer high-strength low-alloy (HSLA) steels or micro-alloyed steels. These alloys are engineered to have better mechanical and corrosion resistant than carbon steels for specific conditions. These are not to be confused by the precipitation hardened or aged hardened grades which are classed as high-strength stainless steel or nickel-based alloys. More information on HSLA can be found on the ASM international website.
