15-5 precipitation hardening stainless steel is a martensitic stainless steel with high levels of nickel, copper, and chromium. 15-5 steel features solid strength, toughness, and ductility, with hardness capability and excellent stress corrosion cracking resistance, making it a great option for use in high pressure corrosive environments. 15-5 stainless steel materials are commonly used in chemical and petrochemical applications, food processing, and performs exceptionally well when used for shafts, gears, valves, and fasteners. Standard Specifications include AMS 5659, AMS 5862 and more.
