15-5PH stainless steel (also known by a trade name “XM-12”) is an age-hardening Martensitic stainless steel with approximately 15% Chromium and 5% Nickel. 15-5PH stainless steel is similar to 17-4. However, unlike 17-4PH, 15-5PH stainless steel is typically produced with an additional refining process (remelt). 15-5PH stainless steel can be supplied in ESR (Electroslag Remelt), or VAR (Vacuum Arc Remelt). This refining process is done to remove impuritie and increase homogeneity. 15-5PH stainless steel has excellent corrosion resistance paired with high strength, and can be heat treated to further increase these properties. Compared to 17-4PH, 15-5PH stainless steel has better ductility and formability, while also having improved transverse strength. Common industry/applications for 15-5PH stainless steel include: Aerospace, Food Processing, Chemical processing, Oil and Gas, Pumps and Valves, and Fasteners
