Stainless Steel 17-7PH Flanges are engineered for exceptional strength, flexibility, and corrosion resistance in demanding industrial environments. Manufactured from advanced precipitation-hardening stainless steel, these flanges deliver high tensile strength, excellent fatigue resistance, and outstanding dimensional stability. They perform reliably under high pressure, cyclic loading, and temperature variation without compromising structural integrity. Known for their resilience and adaptability, 17-7PH Flanges are trusted in aerospace, chemical processing, power generation, and precision engineering systems. When pipelines demand durability, consistency, and controlled performance, Stainless Steel 17-7PH Flanges stand as a powerful solution for critical applications worldwide today.
Stainless Steel 17-7 PH flanges are made from a precipitation-hardened alloy containing iron, chromium (17%), nickel (7%), and small amounts of aluminium. This composition offers high strength, excellent fatigue, and good corrosion resistance, particularly in moderate environments. The mechanical properties include a tensile strength of 130-190 ksi (900-1300 MPa) and a yield strength of 95-160 ksi (655-1100 MPa), along with good formability and weldability. These flanges are widely used in aerospace, chemical, and food processing industries, providing high durability, resistance to stress corrosion cracking, and enhanced mechanical performance.
