Incoloy A-286/UNS S66286 sheet/bar/pipe

‌‌Incoloy series alloy is a nickel-iron-chromium alloy used primarily for oxidation and carburizing resistance at high temperatures. ‌
The Incoloy series consists of three main alloys: Incoloy800, Incoloy800H and Incoloy800AT. These alloys are designed to maintain resistance to oxidation and carburizing at elevated temperatures. The nickel content of Incoloy800 is 32%, which makes it resistant to stress corrosion cracking of chloride and insensitive to the precipitation of σ phase, with excellent uniform corrosion resistance ‌.
