40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ～ 60mm when water quenching, and Ф15 ～ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ～ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.
EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.
Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing S420J0 steel equivalent astm 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.
