15-5PH Stainless Steel Bar
Precipitation hardened stainless steel.
Our 15-5PH stainless steel bar stock offers good corrosion resistance with high strength.
15-5PH is an American aerospace-grade martensitic precipitation-hardening stainless steel. The alloy is a variant of 17-4PH alloy developed to offer improved toughness. 15-5PH offers all the attractive performance characteristics of 17-4PH, including excellent ductility and transverse notch toughness - all from a single, low-temperature heat treatment. Heat treatment is conducted at a temperature range of 482°C (900°F) to 621°C (1150°F) though specific figures are dictated by the actual toughness and strength required. The alloy also offers good corrosion resistance, and the mechanical properties are also superior compared to 17-4PH in larger sections.
Commercial Applications
Typical applications for this material include oil and gas sector components , aircraft flap tracks, engine pylons, structural aerospace components, chemical processing equipment and nuclear reactor components .
