Boiler Steel Pipe

  ASTM A285M Gr.B boiler tube is based on high-quality carbon structural steel, and one or several alloying elements are appropriately added to improve the mechanical properties, toughness and hardenability of the steel. Products made from this steel usually require heat treatment (normalizing or tempering); parts made from it usually require tempering or surface chemical treatment (carburizing, nitriding, etc.) before use. Quenching or high-frequency quenching and other treatments. API 5L seamless steel pipe, therefore, according to the chemical composition (mainly carbon content), heat treatment process and application, this type of steel can be roughly divided into three types: carburized steel, quenched and tempered steel and nitrided steel. ——High-quality carbon structural steel, appropriately adding one or several alloying elements to improve the mechanical properties, toughness and hardenability of the steel. Products made from carbon steel pipe usually require heat treatment (normalizing or quenching and tempering); parts made from it usually require quenching and tempering or surface chemical treatment (carburizing, nitriding, etc.) before use. Cold-drawn seamless steel pipe or high-frequency quenching and other treatments. Therefore, according to chemical composition (mainly carbon content), heat treatment process and application, this type of steel can be roughly divided into three types: nitrided steel, carbon steel, and seamless steel. . High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high-pressure boilers.
