Our firm commitment to excellence has enabled us to provide a wide variety of products that serve the requirements of various industries. Our best-selling products include Super Duplex Steel Fasteners (S32760), which have exceptional strength, corrosion resistance, and durability in severe conditions. We take pride in delivering on time, so that our customers receive the products they require at the time they require them.
Super Duplex Steel S32760 is an alloy with high performance, which consists of about 25% chromium, 4% nickel, 7% molybdenum, and small amounts of nitrogen, and the rest is iron. Due to this special composition, it possesses superior strength, corrosion resistance, and pitting resistance. Its mechanical properties are a minimum tensile strength of 80 ksi (550 MPa) and yield strength of 50 ksi (345 MPa). The material shows high resistance to stress corrosion cracking and crevice corrosion. Physically, it possesses a density of 7.8 g/cm³, and a melting point of approximately 1350°C (2462°F), suitable for challenging applications in severe conditions.
