GH1180 (GH180) superalloy, round bar, strip, plate, wire, sheet, GH1180 (GH180) superalloy is a solution-strengthened deformed superalloy based on Fe-Ni-Cr. Under the conditions of use below 1000 meters, it shows excellent high-temperature corrosion resistance and good process characteristics, and has good microstructure stability. The alloy is equally good for machining and welding, and can be easily formed in both hot and cold work. Therefore, it is widely used to make parts that require high temperatures and long hours of operation under harsh corrosive media.
In the petrochemical industry, GH1180 (GH180) alloy is often used in the manufacture of coal-contact pipes, convection pipes, cracking pipes, etc. In addition, it is also used in the manufacture of radiant tubes, stills and different types of furnace fixtures in various heat treatment furnaces or heating furnaces. In power plants, this alloy is used to make heat exchangers. In the paper industry, the GH1180 (GH180) alloy is used in the manufacture of equipment such as liquid stills.
GH1180 (GH180) alloy has good resistance to stress corrosion, and can still maintain high resistance to stress corrosion cracking in aqueous chlorides. At the same time, it has good corrosion resistance to a variety of acids, such as nitric acid, formic acid, acetic acid, propionic acid, etc.
In the chemical composition of this alloy, carbon (C), chromium (Cr), nickel (Ni), aluminum (Al), titanium (Ti), iron (Fe) and other elements have a certain content range. For example, the chromium content range is 190%～23.0%, the nickel content range is 300%～35.0%。The content of titanium and aluminium does not exceed 06% and 06%。
In terms of heat treatment, GH1180 (GH180) alloy bars, hot-rolled plates, cold-rolled plates, seamless tubes, cold-rolled strips and forgings all need to undergo heat treatment of 1000-1060 and be cooled by air cooling. This treatment ensures the excellent performance and stability of the alloy.
In general, GH1180 (GH180) superalloy is a high-performance material with a wide range of uses, and its excellent corrosion resistance and process characteristics make it widely used in petrochemical, power generation, papermaking and other fields.
