Incoloy Alloy 800 ®

Incoloy Alloy 800 ® is an alloy of nickel, chromium and iron. Alloy 800 offers excellent corrosion resistance, strength, heat resistance and solidity up to 1500˚F. At these elevated temperatures resistance to sulfidation, oxidation and carburisation is superb. Its resistance even covers stress corrosion cracking and loss of toughness and ductility in sigma-phase embrittlement.
