Ferralium 255-SD50 has much higher strength than other commercially available superduplex alloys. Ferralium 255 is the original superduplex stainless steel, noted for its unique combination of mechanical properties and resistance to corrosion, erosion, and cavitation. It has especially low impurities giving improved corrosion resistance, and it is used extensively in the offshore and chemical industries. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on forming and machining. Filing Code: SS-1133. Producer or source: Langley Alloys.
