Products > Incoloy 800 Bars

PMI STEEL Incoloy Alloy 800 is an alloy of nickel, iron and chromium. The alloy remains stable and maintains its austenitic structure even after prolonged exposure to high temperatures, making Incoloy 800 a widely used material for equipment requiring corrosion resistance, heat resistance, strength and stability up to 1500°F (816°C). Other properties of the alloy include high strength and resistance to oxidizing, reducing and aqueous environments. Alloy 800 has general corrosion resistance to many aqueous media and, due to its high nickel content, resists stress corrosion cracking.
