Incoloy 800 Wire

 The Incoloy 800 alloy wire has excellent temperature strength and resistance to oxidation and various other chemical conditions like carburization. The alloy offers higher resistance to creep rupturing and chloride ion stress corrosion cracking and intergranular corrosion in the high temperatures. It retains high mechanical strength from room to high temperature ranges.
