Inconel 601 is a nickel-chromium alloy used for applications that require resistance to corrosion and heat. This nickel alloy stands out due to its resistance to high temperature oxidation, remaining highly resistant to oxidation through 2200° F. Alloy 601 develops a tightly adherent oxide scale which resists spalling even under conditions of severe thermal cycling. This nickel alloy has good high temperature strength, and retains its ductility after long service exposure. It has good resistance to aqueous corrosion, high mechanical strength, and is readily formed, machined and welded. Inconel 601’s properties make it a material of broad utility in fields like thermal processing, chemical processing, pollution control, aerospace, and power generation. However, alloy 601 is not suggested for use in strongly reducing, sulfur bearing environments.
