The Fasteners Mart, with headquarters in Mumbai, India, is a reliable name in the fastener market, supplying precision-engineered parts to world industries. One of their advanced product offerings is the Super Duplex Steel Washer S32760, manufactured by a high-performance super duplex stainless steel alloy. These washers come in several shapes such as flat, spring, and custom shapes, with better sealing, load distribution, and structural properties. Made from UNS S32760 grade, they have great mechanical strength, corrosion resistance, and durability and are suitable for harsh environments like offshore, marine, chemical, and industrial purposes.
Super Duplex Steel Washers S32760 consist of about 25% chromium, 7% nickel, 3.6% molybdenum, 0.2% nitrogen, and iron as the base material. The alloy possesses high tensile strength (750–930 MPa) and yield strength (~550 MPa), providing outstanding performance under stress. The material has outstanding pitting and crevice corrosion resistance, particularly in chloride-rich and acidic environments. Having a density of 7.8 g/cm³ and melting point of approximately 1350°C, it retains strength at elevated temperatures and delivers exceptional fatigue resistance and is, therefore, well suited for long-term usage under rigorous industrial conditions.
