ASTM 1040 Boiler Steel Pipe

 ASTM 1040 boiler tube is based on high-quality seamless 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 ASTM 1040 steel typically require heat treatment prior to use (normalized parts made from it typically require tempering or surface chemical treatment (carburizing, nitriding, etc.). Hardening or induction hardening. Therefore, depending on 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 with one or more alloys added appropriately Elements improve the mechanical properties, toughness and hardenability of steel. Products made of carbon steel pipes usually require heat treatment (normalizing or tempering); parts made of 1040 usually require tempering or chemical treatment (carburizing, nitriding) etc.). The seamless pipe is cold drawn or induction quenched before use. Therefore, depending on the chemical composition of c (mainly carbon content), heat treatment process and application, this type of steel can be roughly divided into nitride steel, carbon steel And three kinds of seamless steel.General boiler tubes are mainly used to manufacture water-cooled wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc. ②High-pressure boiler tubes are mainly used for To manufacture superheater tubes, reheater tubes, gas ducts, main steam tubes, etc. of high pressure and ultra-high pressure boilers
