Super Duplex S32760 Flanges & Fittings in Stock – Forged, Buttweld & Olets. Full Range of Sizes & Classes. Immediate Dispatch Available.
A leading name in industrial piping solutions, our company specializes in the supply of high-grade stainless steels and alloy products for critical applications across industries. Among our premium offerings is Super Duplex Stainless Steel S32760, a highly alloyed duplex grade known for its exceptional strength and superior resistance to corrosion, especially in chloride-laden and aggressive environments. With a balanced composition of 25% chromium, 7% nickel, 3.6% molybdenum, and added tungsten and copper, this alloy is designed to perform reliably in demanding sectors such as offshore, chemical processing, and marine systems.
We supply a comprehensive range of S32760 components, including flanges (weld neck, blind, slip-on, threaded, socket weld), buttweld fittings (long/short radius elbows, tees, reducers, caps), and forged fittings (socket weld & threaded types like elbows, tees, unions, couplings). We also offer specialized branch fittings like weldolets, sockolets, and threadolets that are critical in high-pressure pipeline systems. All products adhere to recognized international material and dimensional standards such as ASTM A182, ASTM A815, ASTM A790, and ASME/ANSI B16.5, B16.9, B16.11, ensuring high precision and universal compatibility.
Super Duplex S32760 exhibits high mechanical strength, with tensile strength up to 800 MPa and yield strength above 550 MPa. The alloy performs reliably in temperatures up to 250–300°C, offering superior resistance to localized corrosion including pitting, crevice corrosion, and stress corrosion cracking. Product sizes are available from ½” NB to 48” NB, with forged fittings offered in pressure classes from 3000# to 9000#. Each product is tested rigorously using PMI, hydro testing, ultrasonic testing, and other NDT methods, and manufactured under a strict ISO 9001:2015 certified quality management system to ensure consistency and reliability.
Due to its excellent resistance properties and mechanical durability, Super Duplex S32760 is extensively used in offshore platforms, desalination plants, subsea pipelines, chemical tanks, heat exchangers, and structural components exposed to seawater or harsh chemicals. The key advantages include exceptional corrosion resistance, high fatigue and impact strength, long operational life, and low maintenance needs. Its low thermal expansion, high strength-to-weight ratio, and good weldability make it a cost-effective solution for critical systems where failure is not an option.
Supplying Super Duplex S32760 Pipe Fittings & Flanges – WNRF, SORF, Blind, Elbows, Tees, Reducers, Forged Fittings, Olets as per ASME B16.5, B16.9, B16.11, MSS SP-44 – Series A/B, Pressure Class up to 2500#.
