Ismail Flanges, a specialist manufacturer and supplier of Stainless Steel 17-7 PH Flanges with headquarters in Jakarta, Indonesia, is renowned for providing flange solutions that are both corrosion-resistant and highly strong. The precipitation-hardened stainless steel alloy SS 17-7 PH offers superior dimensional stability and mechanical qualities at elevated temperatures. These flanges are perfect for applications requiring high strength and fatigue resistance, such as nuclear, petrochemical, marine, and aerospace. Ismail Flanges provides dependable, precisely engineered flanges that satisfy international standards and function well under demanding service conditions by utilising cutting-edge production technologies and strict quality controls.
The main constituents of stainless steel 17-7 PH flanges are 17% chromium and 7% nickel, with 0.75–1.50% aluminium added to aid in precipitation hardening. With a tensile strength of up to 1310 MPa, yield strength of 1170 MPa, and elongation of roughly 6–10%, the alloy demonstrates remarkable strength following heat treatment. Comparable to SS 304, 17-7 PH has good corrosion resistance and retains its mechanical qualities up to 600°F (316°C). Because of this, it is the perfect material for high-stress situations that call for strength and moderate corrosion resistance over time.
