Renine Metalloys is a reliable Super Duplex Steel Fasteners supplier and exporter in Houston for quality products and service. These fasteners are produced from high strength super duplex steel which provides excellent corrosion, stress, and fatigue resistance. They are used in offshore rigs, petrochemical plants, heat exchangers, marine equipment, and structural uses. We are ISO certified and provide fasteners in custom sizes to suit specific project requirements. Offered in grades like UNS S32750, S32760, and S32950.
Super Duplex Steel Fasteners combine high chromium and molybdenum content, which provides high strength and excellent corrosion resistance in harsh environments. Manufactured to ASTM A240 and ASME SA240 specifications. The thickness ranges from 1 mm to 100 mm, and lengths go from 3 mm up to 200 mm. Available sizes include M02 to M30. We offer in various types including bolts, nuts, washers, stud bolts, screws, and threaded rods.
Each fastener can be coated with protective finishes such as black oxide, cadmium, zinc, galvanized, Teflon, Xylan, or other custom coatings. These coatings improve durability, reduce wear, and protect against corrosion. The material composition provides a strong mechanical base with superior pitting and crevice corrosion resistance, especially in saltwater or chemical-rich areas. Their high strength-to-weight ratio makes them suitable for heavy duty applications.
Our fasteners follow ASTM, BS and IS standards. We provide secure fast delivery with packaging options such as pallets, cartons, small boxes, or custom orders. Each batch is quality tested, including hardness testing, tensile testing, material examination, shell pressure testing, impact testing, and visual inspection. Our experts offer the best customer support to clients globally.
