We are a trusted supplier of high-performance alloys, delivering premium-grade materials to industries operating in chemically aggressive and high-temperature environments. Among our wide range of corrosion-resistant alloys, Hastelloy C22 stands out as a superior nickel-chromium-molybdenum-tungsten alloy. Known for its excellent resistance to oxidizing and reducing agents, C22 is ideal for use in chemical processing, marine industries, flue gas scrubbers, and wastewater treatment plants, offering long-lasting durability even in the most challenging conditions. Our offerings in Hastelloy C22 include a complete portfolio of flanges (weld neck, slip-on, blind, threaded, socket weld, lap joint), buttweld pipe fittings (elbows, tees, reducers, caps, stub ends), and forged fittings (socket weld/threaded elbows, tees, couplings, unions). We also supply olet fittings such as weldolets, sockolets, and threadolets designed for high-integrity branching in pipelines. Each product is manufactured in accordance with key standards like ASTM B366, B564, B622, B626, and follows dimensional specifications set by ASME/ANSI B16.5, B16.9, and B16.11. Hastelloy C22 delivers excellent mechanical strength, with tensile strength up to 690 MPa and resistance to pitting, crevice corrosion, and stress corrosion cracking. It performs reliably in a wide range of chemicals, including chlorides, ferric and cupric salts, and strong oxidizers. We provide C22 products in sizes from ½” NB to 48” NB, with pressure ratings from 150# to 2500# for flanges, and 3000# to 9000# for forged fittings. All materials are tested under a certified ISO 9001:2015 quality management system, including PMI, hydro, ultrasonic, hardness, and dimensional checks to ensure top-tier performance. Hastelloy C22 is widely used in chemical reactors, heat exchangers, digesters, pollution control systems, offshore platforms, and marine exhausts. Its main benefits include resistance to a wide variety of acidic and mixed chemical environments, high strength…
