Stainless Steel 347 Flat Face Flanges

Stainless Steel 347 Flat Face Flanges are highly versatile and known for their superior mechanical properties and resistance to corrosion. At the heart of their remarkable performance lies their unique chemical composition. Primarily comprised of iron, these flanges also contain a blend of other essential elements such as chromium, nickel, and columbium. With a chromium content ranging between 17% and 19%, and a nickel content varying from 9% to 13%, Stainless Steel 347 Flat Face Flanges acquire their remarkable corrosion resistance and durability. The columbium inclusion, present in amounts between 10X carbon (minimum) and 1% (maximum), provides stabilization, preventing carbide precipitation during welding and elevated temperature operations. This stabilization further enhances the flanges' resistance to intergranular corrosion and other related phenomena, making them the material of choice for diverse industries like petrochemical, power generation, and chemical processing. The secret to their superior performance lies in their carefully balanced chemical composition, which offers engineers and designers a highly sought-after combination of strength, durability, and resistance in diverse environmental conditions.

SS 347 Flat Face Flanges are uniquely positioned in piping applications due to their exceptional properties and versatile uses. Being corrosion-resistant and formable, these flanges are perfect for operating in extreme environments, such as high temperatures and pressures, withstanding aggressive chemicals and providing long-lasting durability. Their enhanced resistance to intergranular corrosion, owing to the addition of columbium and tantalum elements, makes them particularly desirable for heavy-duty industrial applications such as chemical, petrochemical, and power generation. The flat-face design of these flanges allows for easy installation and dismantling, ensuring optimal efficiency and reduced maintenance costs. Moreover, their availability in various dimensions, pressure levels, and sizes makes them a go-to choice for engineers and construction specialists when dealing with complex design requirements or demanding conditions.
