UNS S32760 (commonly known under trade names such as Zeron 100 or Super Duplex F55) is a premium super-duplex stainless steel alloy with a balanced austenitic/ferritic microstructure. Its high alloying content — typically 24–26 % chromium, ~6–8 % nickel, ~3–4 % molybdenum, copper, tungsten and nitrogen additions — gives it outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride and harsh environments. The alloy also delivers elevated mechanical strength (yield, ultimate, fatigue) and superior toughness compared to conventional stainless steels.
As a Socket Weld Raised Face (SWRF) flange in S32760, this component offers compact, high-integrity joints especially in small bore piping systems. The socket weld design allows the pipe to be inserted into the flange bore and welded fillet-wise, providing a robust joint that is more compact than a butt weld. For systems where alignment, space constraints or ease of installation matter, S32760 SWRF flanges by a supplier like Synergy Engineering Solution form a compelling option. Through precise machining and quality control, the flange’s internal bore and face are made to tight tolerances to ensure fit and sealing integrity.
Synergy Engineering Solution acts as a manufacturer, stockist, and global exporter of these S32760 SWRF flanges. They maintain inventories of standard sizes and classes for prompt supply, while also offering custom fabrication for project-specific dimensions or specifications. Their export markets span the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada) and Africa. Their logistics and export infrastructure are adapted to handle high-grade alloy flanges — including sturdy export packing, documentation (Mill Test Certificates, inspection reports), compliance with import regulations, and coordination with freight forwarders.
In terms of performance, typical mechanical data for S32760 in the annealed condition includes a 0.2 % proof (yield) strength in the neighborhood of ~550 MPa, ultimate tensile strengths up to ~750–900 MPa, elongation ~25 %, Brinell hardness up to ~270 HB, and good impact toughness even at subzero temperatures. The alloy can maintain integrity in corrosive chloride media, with a Pitting Resistance Equivalent Number (PREn) ≥ 40, which underlines its suitability for seawater, saline, brackish, or aggressive chemical environments.
Applications for S32760 SWRF flanges are diverse. They find use in offshore and subsea piping tie-ins, seawater cooling systems, desalination circulation lines, chemical and petrochemical process piping, and in systems transporting acids, chlorides or sour gases. Designers often prefer them where weight savings and thinner wall sections are beneficial but corrosion performance must not be compromised. A supplier like Synergy would support customers with engineering guidance, verifying welding procedures, flange-to-pipe compatibility, and recommending companion fasteners and gasketing to match the high-performance alloy.
By leveraging advanced manufacturing processes, strict quality assurance, and a robust global supply network, Synergy Engineering Solution & Exporter continues to be a preferred source for UNS S32760 Super Duplex Steel WNRF Flanges worldwide. Whether it’s for marine, offshore, chemical, or power generation applications, these flanges guarantee excellent strength, superior corrosion protection, and long service life — making them an essential component in any critical piping system.
