Special AlloysSheet/Plate
Description (English)
Inconel 600 combines a high nickel content for resistance to reducing environments and caustic corrosion with a high chromium content for resistance to oxidizing environments. The alloy resists chloride-ion stress-corrosion cracking, making it suitable for use in chloride-containing environments where stainless steels would fail. It maintains useful strength and toughness at both cryogenic temperatures and elevated temperatures up to 1095 °C, and resists oxidation and scaling in continuous service to 1175 °C and intermittent service to 1035 °C. The alloy is not age-hardenable; strengthening is achieved only by cold work. It is approved for nuclear core applications (ASME Section III).
