Pipeline steel plays an important role in pipeline transportation. How many types of chemical composition of NM400, pipeline steel are there? At present, pipeline steel can be divided into the following four categories according to microstructure. First, pearlitic pipeline steel. The basic components of pearlitic pipeline steel are carbon and manganese, generally speaking, the content is 0.10% - 0.20%, and the manganese content is 1.30% - 1.70%. It is generally produced by hot rolling or normalizing heat treatment process. Second, acicular ferrite pipeline steel. Third, martensitic pipeline steel. Fourth, tempered sorbite pipeline steel.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing chemical composition of NM400 steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.
