After the heat treatment of the 45# seamless steel pipe, it is necessary to wait for it to cool before proceeding to the next step. The cooling method of 45# seamless steel pipe changes with the change of its manufacturing materials. For most steels, natural cooling can be used. For some special 45# seamless steel pipes, to ensure its Organizational state, physical properties and mechanical properties are developing in the expected direction, and certain methods and systems must be adopted.

　　The chemical composition specified in the general standard refers to the smelting component. It refers to the chemical composition of the 45# seamless steel pipe after smelting and pouring. In order to make it representative, the analysis is carried out according to the specified standard method (GB/T223).
