42CrMo4 material is an alloy structural steel with high strength, high hardenability, good toughness, small deformation during quenching, and high creep strength and endurance strength at high temperatures. 42CrMo4 steel is a modified AISI 4140 steel. The EN 10025 S550QL high strength steel product is mainly used in the manufacturing of seamless hydraulic cylinder or gas cylinder, heavy machinery, cranes, excavators and forklifts, etc.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while EN 10025 S550QL high strength steel steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of EN 10025 S550QL high strength steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
