Alloy 601 is nickel-chromium-iron alloy used for the general-applications that require resistance to heat and corrosion. An outstanding characteristic alloy 601 is its resistance to high temperature oxidation. 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. However, alloy 601 is not suggested for use in strongly reducing, sulfur bearing environments.
