Corrosion resistance of Inconel600 bolts

Alloy 600 is corrosion resistant to various corrosive media. The composition of chromium gives this alloy better corrosion resistance under oxidizing conditions than Nickel 99.2 (Alloy 200) and Nickel 99.2 (Alloy 201, low carbon). At the same time, the higher nickel content gives the alloy good corrosion resistance in reducing conditions and alkaline solutions, and can effectively prevent chlorine-iron stress corrosion cracking. Alloy 600 has good corrosion resistance in organic acids such as acetic acid, acetic acid, formic acid, and stearic acid, and moderate corrosion resistance in inorganic acids. It has excellent corrosion resistance in high-purity water used in primary and secondary circulation in nuclear reactors. The particularly outstanding performance of 600 is its ability to resist the corrosion of dry ammonia and hydrogen ammonia, and the application temperature can reach 650°C. At high temperatures, the annealed and solution-treated alloys have good resistance to oxidation spalling and high strength in the air. The alloy can also resist ammonia gas and nitriding and carburizing atmospheres, but when the redox conditions alternate, the alloy will be corroded by partially oxidizing media (such as green death liquid)
