High strength F55 UNS S32760 duplex stainless steel round bar XM-19 hot-rolled solid bar
Introduction to UNS S32760 Material:
S32760 is a high-performance super duplex stainless steel material with high strength and corrosion resistance.
S32760 stainless steel, also known as super duplex steel, is a high alloy material mainly used in various strong corrosive environments. Its tensile strength ranges from 750 to 895 MPa, yield strength is greater than 550 MPa, and elongation is greater than 25%, demonstrating excellent mechanical properties. The chemical composition of this material includes elements such as carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, tungsten, copper, and nitrogen. Among them, the high content of chromium and nickel endows it with strong oxide film protection, while the added elements such as molybdenum and nitrogen further enhance its corrosion resistance in wear, erosion, and other aspects.
