GH1180 (NS111) is a Fe-Ni-Cr solution-strengthened deformed superalloy, which is widely used in high temperature environments below 1000. This alloy exhibits stable microstructure properties due to its excellent resistance to high-temperature corrosion and good process properties. GH1180 exhibits excellent properties during both machining and welding, making it easy to form by a variety of hot and cold processing methods. 
Due to its unique material properties, GH1180 is particularly suitable for components that require long periods of high temperature operation in harsh corrosive media. In the petrochemical industry, it is widely used to make key components such as coal contact pipes, convection pipes, and pyrolysis pipes. In addition, GH1180 is also used as radiant tubes, distillers, and different types of furnace fixtures in heat treatment furnaces or heating furnaces. This alloy is also commonly used in heat exchangers in power plants and in liquid distillers in the paper industry. 
Tinggang provides a variety of GH1180 product forms, including hot-rolled and forged bars, hot-rolled plates, cold-rolled sheets, cold-rolled (drawn) seamless tubes, cold-rolled strips and forgings, etc., to meet the diverse needs of different fields. In order to ensure the reliability of product quality, GH1180 material follows a series of strict technical standards, such as GB T 15007 corrosion-resistant alloy grade, GB T 15008 corrosion-resistant alloy rod, etc. 
In terms of chemical composition, the elemental mass fraction of GH1180 is precisely controlled to ensure its excellent performance. The carbon (c) content does not exceed 010%, manganese (Mn) content does not exceed 150%。The chromium (CR) content is 1900～23.00% between the nickel (Ni) content of 3000～35.00%. In addition, the content of aluminum (Al) is controlled at 015～0.60%, silicon (Si) content does not exceed 100%。The content of phosphorus (P) and sulfur (S) is limited to 0., respectively030% and 0015% or less. The content of titanium (Ti) is 015～0.60%, while the copper (Cu) content does not exceed 075%。The rest is the element iron (Fe). These precise chemical compositions guarantee superior performance of GH1180 alloy in high-temperature and corrosive environments.
