Corrosion resistance of Inconel 601:
An important property of this alloy is its resistance to oxidation at temperatures up to 1180°C. Even under harsh conditions, such as heating and cooling cycles, Inconel 601 produces a dense oxide film, resulting in high peel resistance. Inconel 601 has good carbonation resistance. Due to its high chromium and aluminum content, Inconel 601 has good oxidation resistance in high-temperature sulfur-containing atmospheres. Inconel 6601 alloy is corrosion-resistant to various corrosive media. Because it contains chromium, it is more resistant to corrosion than pure nickel (Alloy 200/201) under oxidizing conditions. At the same time, it contains a large amount of nickel, which gives the alloy good corrosion resistance in reducing conditions and alkaline solutions. Additionally, it is highly resistant to stress corrosion cracking.
It 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. The high-purity water used in the primary and secondary cycles of nuclear reactors has good corrosion resistance. It can resist the corrosion of dry chlorine and hydrogen chloride, and the service temperature can reach 650℃.
At high temperatures, the annealed and solid solution states of the alloy have good resistance to oxidation peeling and high strength in the air, and can withstand high temperatures of 1100°C in a continuous air oxidation environment. In reducing gases (H2 or CO) that do not contain or (ions), it can withstand high temperatures of 1150°C. Oxidizing gases containing th(ion) (such as sulfurous acid-containing air) can be used at temperatures up to 815°C. However, in reducing gas containing hydrogen sulfide, the upper limit temperature is 535°C. In addition, it will not become embrittled in high temperature environments of 550 to 750°C.
Resistant to nitrogen, hydrogen, ammonia and carburizing gases. Although it has a weak wetting effect on chlorine and bromine, it is very effective at treating hydrogen chloride and chlorine at high temperatures. Hydrogen chloride can reach 540°C, and chlorine gas can be used at 510°C. However, when the redox conditions alternate, it will be corroded by some oxidizing media (such as green waste liquid).
