15CrMo boiler tube is based on high-quality carbon structural steel, with one or several alloying elements appropriately added to improve the mechanical properties, toughness and hardenability of the steel. Products made of this type of steel usually need heat treatment (normalizing or quenching and tempering); the parts and components made of it usually need to undergo quenching and tempering or surface chemical treatment (carburizing, nitriding, etc.) before use. Quenching or high-frequency quenching and other treatments. API 5L Sseamless Steel Pipe,Therefore, according to different chemical composition (mainly carbon content), heat treatment process and application, this type of steel can be roughly divided into three types: carburizing, quenched and tempered and nitrided steel.is based on high-quality carbon structural steel, with one or several alloying elements appropriately added to improve the mechanical properties, toughness and hardenability of the steel.
