Incoloy is a nickel-chromium-iron alloy designed to resist oxidation and carburization at elevated temperatures.
Properties: Nickel-chromium-iron alloy； Function: Anti-oxidation and carburization
Category: Incoloy800, Incoloy800H, Incoloy800HT, Incoloy825，incoloy925、incoloy926、incoloy901 etc.
The main products of this alloy are fasteners ,flanges, round bars, pipes, plates, strips, wires and forgings, etc., which are mainly used in nuclear industry, petrochemical industry, chemistry, food and other industries.
This alloy is a nickel-iron-chromium iron-nickel-based corrosion-resistant alloy. This alloy has good corrosion resistance in high-temperature water vapor, including steam-air-CO2 mixed gas. In some high-temperature and high-pressure water media, its stress corrosion resistance is significantly better than 18-8 stainless steel and Inconel600; it also has good corrosion resistance in H2+H2S medium, and in alkaline media containing NaOH, its stress corrosion resistance is better than Inconel600 and other high-nickel alloys.
