Elvis Nickel Alloys, located in Houston, USA, stands out as a top manufacturer and supplier of Super Duplex Steel Flanges S32750. These flanges are celebrated for their remarkable mechanical strength and impressive resistance to corrosion. Made from UNS S32750 (SAF 2507), they boast a dual-phase microstructure (austenitic-ferritic), which provides excellent protection against pitting, crevice corrosion, and chloride stress corrosion cracking, even in tough environments. You can find them in various styles, including weld neck, slip-on, blind, socket weld, and lap joint, all adhering to global standards like ASTM A182, ASME B16.5, and EN 1092-1, making them perfect for high-performance piping systems.
Super Duplex Steel S32750 Flanges generally consist of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with trace amounts of manganese, silicon, and copper. These components help achieve a high PREN (>40), ensuring outstanding resistance to localized corrosion. The flanges can handle tensile strength up to 800 MPa and yield strength of at least 550 MPa, along with remarkable impact resistance at both room and sub-zero temperatures. This blend of high strength and corrosion resistance makes them perfect for demanding service conditions that require durable, leak-proof connections.
