Inconel 600 is a nickel-chromium-iron alloy that is used in extreme conditions. Its usual content is approximately 72% nickel, 14–17% chromium, and 6–10% iron, providing superior resistance to oxidation, carburization, and chloride-ion stress corrosion cracking. These buttweld fittings are highly strong mechanically with a tensile strength of approximately 655 MPa and yield strength close to 310 MPa. They maintain structural integrity up to 1093°C at higher temperatures. Inconel 600 possesses satisfactory weldability and toughness and therefore finds itself in favor as a fabricating material for heat-resistant and corrosive service exposure.
