Honesty Steel & Alloys Ltd. is a manufacturer, exporter, and supplier of Super Duplex Steel S32750/S32760 Fasteners, offering high-performance fastening solutions for demanding industrial applications. Super Duplex stainless steel combines high mechanical strength with excellent resistance to pitting, crevice corrosion, chloride-induced corrosion, and stress corrosion cracking.

UNS S32750/ is commonly identified with ASTM A182 F53, while UNS S32760 corresponds to ASTM A182 F55. Both grades contain approximately 24–26% chromium and 6–8% nickel, with molybdenum and nitrogen providing high corrosion resistance. S32760 additionally contains copper and tungsten within its specified chemistry.

Super Duplex S32750/S32760 Hex Bolts are heavy-duty threaded fasteners used where high strength and corrosion resistance are required simultaneously. Their duplex microstructure provides substantially higher strength than conventional 300-series stainless steel grades while maintaining strong resistance to chloride-related corrosion.

Super Duplex S32750/S32760 Screws are used for equipment, machinery and structural assemblies where conventional stainless steel screws may not provide adequate strength or corrosion resistance. Available configurations include socket head cap screws, machine screws, set screws, countersunk screws and other custom designs.

Super Duplex Steel S32750/S32760 Washers are used together with bolts and nuts to distribute the applied load over a larger surface area and help protect connected components. Plain, flat, spring and customized washer designs can be supplied.

S32750 is also known as Super Duplex 2507, UNS S32750, ASTM A182 F53, and Werkstoff 1.4410. The grade contains 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.24–0.32% nitrogen. UNS S32760 is commonly designated ASTM A182 F55 and Werkstoff 1.4501. Its chemistry includes chromium, nickel, molybdenum, nitrogen, copper, and tungsten. The addition of copper and tungsten distinguishes S32760 from S32750 and contributes to its performance in selected aggressive environments.
