Our Stainless Steel 309 Flanges are fabricated from a strong austenitic stainless steel alloy consisting of 25% chromium and 20% nickel for excellent resistance to oxidation and high-temperature modulus. These flanges have some design constraints regarding their application, inclusions, or heating elements that often contemplate use in aircraft parts and annealing processes. Sankalp Alloys Overseas deals in a comprehensive range of Stainless Steel 309 Flanges, offering several functional diameter, size, and wall thickness variations. These SS 309 Flanges are annealed at 1038°C, then rapidly quenched in water, for the development of optimal properties for mentor high resistance to marine atmospheres, improving overall performance.

With high weldability and a balanced composition of chromium to nickel, these flanges are engineered to give you cost-effective solutions without compromising on quality. Our inventory includes a wide range of Stainless Steel 309 Flanges like SS 309 Slip-On Flanges, SS 309 Weld Neck Flanges, SS 309 Blind Flanges, SS 309 Lap Joint Flanges, SS 309 Pipe Flanges, and SS 309 Socket Weld Flanges.
