Incoloy Ni-Fe-Cr alloys 800/800H/800HT offer high-temperature strength and resistance to oxidation. The higher nickel content makes it have good resistance to stress corrosion cracking in water corrosion conditions. The addition of chromium makes it have better resistance to spot corrosion and crack corrosion cracking. The 800 series alloy has good resistance to nitric acid, organic acid corrosion even in the water up to 500℃ of the extremely high-temperature medium, but limited in sulfuric acid and hydrochloric acid.
