Alloy 600 is resistant to all kinds of corrosive media. The chromium composition gives the alloy better corrosion resistance under oxidation conditions than nickel 99.2(alloy 200) and nickel 99.2(alloy 201 low carbon). At the same time, the higher nickel content makes the alloy have good corrosion resistance in reduction conditions and alkaline solutions, and can effectively prevent chlorine-iron stress corrosion cracking. Alloy 600 has good corrosion resistance in acetic acid, acetic acid, formic acid, stearic acid and other organic acids, and moderate corrosion resistance in inorganic acids. The high purity water used for primary and secondary circulation in nuclear reactors has excellent corrosion resistance. The 600 is particularly resistant to corrosion by dry chlorine and hydrogen chloride at 650℃. At high temperature, the annealed and solution treated alloys have good oxidation resistance and high strength in air. The alloy can also resist ammonia and nitriding and carburizing atmosphere, but when the REDOX conditions change alternately, the alloy will be corroded by some oxidizing media (such as green dead liquid).
