Super Duplex Steel S32750 Fasteners
Super Duplex Steel S32750 Fasteners are known for their strength and corrosion resistance in harsh environments. Metracore Alloys is a leading uns s32750 fasteners manufacturer with precision to meet global standards. The grade contains chromium (24–26%), molybdenum (3–5%), nickel (6–8%), and nitrogen (0.24–0.32%), giving it high pitting resistance and excellent toughness. With a density of 7.8 g/cm³ and a melting point of 1350°C, ASTM A479 UNS S32750 fasteners maintain stability in extreme heat and pressure conditions.
Super Duplex Steel S32750 Fasteners, ASTM A479 S32750, ASTM A479 UNS S32750, Super Duplex 2507 Bolts, Super Duplex Steel S32750 Nuts, Super Duplex UNS S32750 Washers
We offer fasteners in a wide range of sizes and forms. Standard sizes are 3 mm to 200 mm, with bolt and screw sizes from M3 to M56, and nuts available in the same range. Washers vary from M1 to M64, while lengths range from M02 to M33. Customers can also request custom sizes to fit specific needs. The line includes Super Duplex 2507 bolts, nuts, washers, and U screws, all of which are designed to provide continuous strength and dependability.
Super Duplex 2507 fasteners are widely used in offshore platforms, chemical processing, pressure vessels and marine applications. Their resistance to chloride stress cracking makes them appropriate for use in seawater and oilfield applications. The manufacturing process includes forging, heat treatment, and machining to provide durability and precise dimensions. Each fastener is tested for mechanical strength and corrosion performance before dispatch.
