Alloy 800 Flanges Manufacturer in India
Alloy 800 is a nickel-iron-chromium alloy that is characterized by good strength, ductility and stability even at high temperatures, thus suitable in high-performance industrial applications. It exhibits excellent oxidation, carburization and stress corrosion cracking resistance even in extreme heat environments. Alloy 800 Flanges are highly utilized in piping systems that need high thermal conductivity, mechanical stability, and stability. These flanges are used in high pressure and high temperature applications to achieve high structural integrity and non-leaking connections in chemical processing industry, petrochemical plants, refineries, power generation units, nuclear power plants, heat exchangers, thermal processing systems, furnaces and applications of high temperature process pipes.
What Are Alloy 800 Flanges?
Alloy 800 flanges compliant with the ASTM B 564 / UNS N 08800 standards are being produced using forged and rolled nickel alloy to be used as a high-performance piping system. It is a balanced alloy of nickel, chromium and iron that offers great resistance to oxidation, carburization as well as chloride stress corrosion cracking. Alloy 800 flanges are also designed to be used in systems that have extreme temperatures, high industrial media and constant thermal forces. They find application in heat exchangers, tubing systems in nuclear steam generators, process piping, casings on heating elements, carburizing equipment, chemical plants, refineries, power plants, and thermal processing industries where strength, thermal stability, and long service life are required.
