Alloy 600

• Heat treating muffles and retorts
• Vacuum furnace fixtures
• Nitriding furnaces and baskets
• Chlorination equipment to 538°C
• Titanium dioxide plants

With high nickel content, Inconel® Alloy 600 is virtually immune to chloride-induced stress corrosion cracking. The alloy has superb corrosion resistance to caustic environments and resistance to dry chlorine up to 538°C.

This alloy has excellent oxidation resistance up to 1093°C combined with high carburisation resistance and demonstrates good performance in high temperature nitriding environments.

It is not recommended that Inconel® Alloy 600 be used at red heat temperatures where sulphur is present. It has also been found that Inconel® Alloy 600 can fall victim to stress corrosion cracking in hot, concentrated caustic alkalis, however, this can be avoided if the fabrication is fully stress relieved before use. Recommended stress relieving temperature of 982-1010 °C for 1 hour yields the best performance.
