Mira Fasteners is a reliable manufacturer and supplier of **Super Duplex Threaded Rods** based in Kuala Lumpur, Malaysia. They provide high-strength, corrosion-resistant fastening solutions that are perfect for critical industrial applications. Built to withstand tough environments, these threaded rods boast impressive mechanical properties and outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Mira Fasteners offers Super Duplex Threaded Rods in various diameters and lengths, all meeting global quality standards. These rods are commonly used in offshore platforms, petrochemical plants, and marine structures, ensuring they deliver long-lasting and secure performance even in extreme conditions.
Typically made from grades like UNS S32750 and UNS S32760, Super Duplex Threaded Rods contain about 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and nitrogen. This unique composition results in a balanced austenitic-ferritic microstructure, providing excellent tensile strength (up to 800 MPa), high yield strength (over 550 MPa), and remarkable resistance to corrosion and stress. These rods maintain their strength and integrity in high-pressure, high-temperature, and aggressive chemical environments, making them ideal for structural and load-bearing applications in corrosive settings.
