1.8987 EN 10025-6 high strength steel hot working

EN 10025-2 is standard for hot rolled products of structural steels.
EN 10025-2 steel grades are 1.8987 EN 10025-6 high strength steel, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.

Oxygen is a harmful element in 1.8987 EN 10025-6 high strength steel steel. With the increase of oxygen content, the strength of 1.8987 EN 10025-6 high strength steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of 1.8987 EN 10025-6 high strength steel 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 1.8987 EN 10025-6 high strength steel 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.
