Pneumatic high-pressure cage type angle regulating valveValve body material

High temperature materials: When selecting high temperature materials, it is necessary to fully consider the issues of high temperature strength, metallographic structure changes at high temperatures, and corrosion resistance. Generally, alloy steel materials are required to contain chromium, nickel, and molybdenum elements. In addition, under high temperature and pressure, steel is corroded by hydrogen gas, which generally causes decarburization and embrittlement. After adding metal elements such as chromium, nickel, and molybdenum to steel, it combines with carbon elements to improve the steel's resistance to hydrogen corrosion.

Low temperature materials: When selecting low-temperature materials, it is necessary to fully consider the low-temperature impact value of the material, as well as the brittleness problem of the material's toughness decrease at low temperatures. Therefore, materials used in low-temperature conditions must have sufficient toughness at low temperatures, and the steel selected for valves at different temperatures must meet the standard specified impact energy at the applicable temperature in order to be safe and reliable. Austenitic stainless steel is often used due to its stable low-temperature mechanical properties.
