Stainless Steel 347 pipe fittings are austenitic alloys containing chromium and nickel, stabilized with niobium (columbium). This stabilization improves resistance to intergranular corrosion, especially after welding or exposure to elevated temperatures. SS 347 offers good tensile strength, excellent toughness, and superior creep resistance. It maintains mechanical stability, oxidation resistance, and ductility under high-temperature and pressure conditions, making it suitable for continuous service in demanding industrial environments.
