Hastelloy materials are mainly divided into three series: B, C and G, . The main features of Hastelloy valves include their excellent corrosion resistance, which can effectively resist the erosion of various corrosive media. Specifically, Hastelloy B has good corrosion resistance to hydrochloric acid of various concentrations and non-oxidizing salts and acids; Hastelloy C has good corrosion resistance to oxidizing solvents, low-concentration hydrochloric acid and nitric acid at room temperature; and Hastelloy G is particularly suitable for corrosive environments such as sulfuric acid, nitric acid, phosphoric acid and seawater, but is not resistant to halogen acid1. In addition, Hastelloy valves also have good wear resistance and heat resistance, and can operate stably for a long time under high temperature and high pressure environments.
Hastelloy valves are widely used in various industries, such as petroleum, chemical, pharmaceutical, etc. Due to their excellent sealing and corrosion resistance, and can effectively protect production equipment and personnel safety.
