Monel 400 Industrial Fittings & Flanges – Complete Range of Buttweld, Forged & Outlet Types. ISO Certified | Worldwide Delivery. Backed by years of experience in the supply of high-performance alloys, our company offers reliable material solutions to industries operating in corrosive and high-pressure environments. One such solution is Monel 400, a solid-solution alloy primarily composed of nickel (≈63%) and copper (≈30%). Known for its excellent resistance to seawater, acids, and alkalis, Monel 400 maintains its strength and toughness across a wide temperature range. It is widely utilized in marine, chemical, hydrocarbon, and heat exchanger applications due to its outstanding corrosion performance and mechanical stability.We supply a comprehensive range of Monel 400 products, including flanges (weld neck, slip-on, threaded, blind, socket weld, lap joint), buttweld fittings (long/short radius elbows, tees, concentric and eccentric reducers, end caps), and forged fittings such as socket weld and threaded elbows, tees, couplings, and unions. We also offer outlet fittings like weldolets, sockolets, and threadolets suitable for complex piping systems under high pressure. All components are manufactured as per international standards such as ASTM B366, B564, B165, B725, and conform to ASME/ANSI B16.5, B16.9, and B16.11 guidelines.Monel 400 offers a tensile strength of 480–620 MPa and yield strength of around 170–345 MPa, with excellent ductility and impact resistance, even at sub-zero temperatures. It performs exceptionally well in both acidic and alkaline environments, including hydrofluoric and sulfuric acid. Available in sizes ranging from ½” NB to 48” NB, our Monel 400 products are offered in pressure ratings up to 2500# for flanges and 3000# to 9000# for forged fittings. Each item is thoroughly tested — including PMI, ultrasonic, hydrostatic, and visual inspections — and manufactured under a rigorous ISO 9001:2015 certified quality management system.Monel 400 is highly suitable for marine engineering, chemical processing plants, oil refining,…
