At Sunmach we consistently manufacture & export a wide range of Super Duplex Fasteners as like Bolts, Nuts, Washers, Screws & Studs / Threaded Rods exactly catering to our customer´s specifications or drawing with assured quality & timely delivery.

Super Duplex Stainless Steel grades are similar to standard Duplex, but they contain a higher content of chromium, thus enhancing the corrosion resistance and mechanical properties. Super Duplex Stainless steel is designed for applications which demand exceptional strength and corrosion resistance. The high molybdenum, chromium and nitrogen contents of Super Duplex results in excellent resistance to chloride pitting and crevice corrosion attack and the Duplex structure provide with exceptional resistance to chloride stress corrosion cracking.

Super Duplex Fasteners Applications - Desalination equipment, chemical process pressure vessels, piping and heat exchangers, marine applications, flue gas scrubbing equipment, pulp & paper mill equipment, oil industries & gas industries.
