Inconel 600 Corrosion resistance
Alloy 600 have corrosion resistance to many kinds of corrosive media. Chromium content made it with better corrosion resistance than Nickel 99.2 (alloy200) and Nickel 99.2 ( alloy201,low carbon) in the oxidize environment. Meantime, high Nickel content make this alloy with good corrosion resistance in the reduction condition and alkaline solution, and also effective avoid chlorine-iron stress corrosion cracking.
Alloy 600 have good corrosion resistance in the acid, acetic acid, formic acid, stearic acid and other organic acid, with medium corrosion resistance in the inorganic acid. The alloy with excellent corrosion resistance in the first and the second recycling use of the high purity water in the nuclear reactor. Especially excellent corrosion resistance to dry chlorine and chlorine hydride applied up to 650℃.
When nder the high temperature, annealing and state solution alloy have good antioxidant off and high-intensity in the air, 600 can resist the ammonia, nitriding and carburizing atmosphere, but at the turn of the changes in redox conditions, it will be corrosion by parts of oxidation media.( such as green death liquid)
