Inconel 600, known as UNS N06600, is a nickel-chromium alloy with good oxidation resistance at high temperatures and resistance to chloride-ion stress-corrosion cracking, corrosion by high-purity water, and caustic corrosion. Service temperatures for alloy 600 can be from cryogenic to 2000°F (1093℃). This alloy has good workability, weldability, and high strength.
Applications of Inconel 600:
Chemical process industry: heaters, condensers, and trays.
Heat-treat industry: muffles, retorts, baskets, and other furnace fixtures.
Aerospace industry: exhaust liners, turbine seals, and air-frame components.
Nuclear industry: due to its resistance to corrosion in high-purity water.
Normal product forms: Pipes, tubes, sheets, strips, plates, round bars, flat bars, forgings, hexagons, wires, and extruded sections.
