ASTM A403 WP 316L BW 90° Elbows | Pipe Fittings Suppliers
ASTM A403 WP 316L is a low carbon version of 316 stainless steel, mainly used to make corrosion resistant and high strength pipe fittings such as ASTM A403 WP316L pipe fittings, elbows, tees, reducers, etc. We are an ISO 9001 certified stainless steel 316L elbow manufacturer and supplier.
SS 316L butt weld elbows have strong resistance to corrosion and carbide precipitation. ASME SA 403 WP316L butt weld fittings can be processed by cold working technology, and its austenitic chromium-nickel-iron structure is strong and durable at low temperatures. The DIN 1.4435/1.4404 SS seamless pipe fittings we offer can be annealed and hardened by cold working process.
