ASTM ASME 15-5 PH Stainless Steel Pipes & Tubes

Product Description
ASTM/ASME 15-5 PH Stainless Steel Pipes & Tubes are premium precipitation-hardening martensitic (UNS S15500) products conforming to ASTM A312/A213/A790 standards, featuring an optimized chromium (14-15.5%), nickel (3.5-5.5%), and copper (2.5-4.5%) composition with niobium/tantalum stabilization for superior strength (up to 1170 MPa yield in H1150 condition) and enhanced toughness over 17-4 PH. This advanced alloy achieves consistent mechanical properties through precise low-temperature aging (482-621°C) with minimal distortion, making it ideal for aerospace structural components, nuclear reactor parts, and high-pressure hydraulic systems requiring exceptional reliability. The material offers improved transverse ductility and fracture toughness compared to conventional PH steels while maintaining comparable corrosion resistance to 304 stainless, with outstanding resistance to stress corrosion cracking in marine and chemical environments. Available in solution-annealed (Condition A) or various precipitation-hardened states (H900, H1025, H1150), 15-5 PH is particularly valued for critical applications like aircraft fittings, missile components, and petrochemical valves where its combination of high strength, dimensional stability during heat treatment, and superior fatigue life outperform standard martensitic and austenitic grades. The alloy's cleaner composition (reduced impurity elements) ensures better metallurgical consistency for demanding applications requiring stringent property control.
