Incoloy 800, 800H, 800HT Pipe Fittings & Flanges – Complete Range of Buttweld, Forged, and Olet Types. ISO 9001:2015 Certified | Worldwide Delivery. As a trusted supplier of high-performance alloys, we provide engineered metal solutions tailored for use in high-temperature, high-stress, and corrosive environments. Incoloy 800 is a nickel-iron-chromium alloy designed for excellent strength and corrosion resistance, particularly at elevated temperatures. It offers stability against oxidation, carburization, and high-temperature scaling, making it ideal for use in petrochemical plants, heat exchangers, furnace components, and power generation systems.We offer a wide variety of Incoloy 800HT products, including flanges (weld neck, slip-on, socket weld, blind, threaded, lap joint), buttweld pipe fittings (elbows, reducers, tees, caps), and forged fittings (socket weld/threaded elbows, couplings, unions, tees). Additionally, we supply olets such as weldolets, sockolets, and threadolets, suitable for high-temperature branch piping applications. All products conform to international standards including ASTM B564, B366 and are manufactured to meet ASME/ANSI B16.5, B16.9, and B16.11 specifications for dimensional and pressure integrity.Incoloy 800 offers a tensile strength of approximately 520 MPa, excellent resistance to oxidation up to 1100°C (2000°F), and good structural stability at prolonged high-temperature exposure. The material maintains its mechanical properties in environments containing sulfur compounds, nitriding, and other process gases. We supply components in sizes ranging from ½” NB to 48” NB, with pressure ratings from 150# to 2500# for flanges and up to 9000# for forged fittings. Each item is manufactured under a strict ISO 9001:2015 certified quality system, with testing methods including PMI, hydrotesting, ultrasonic, hardness, and dimensional inspections.Incoloy 800H is widely used in thermal processing equipment, hydrocarbon cracking units, steam superheaters, heat exchanger tubing, and high-temperature piping systems. Its advantages include high creep and rupture strength, excellent resistance to oxidation and carburization, and stability in acidic and high-temperature environments. The alloy’s long service…
