What is en10025-4 S420ML equivalent ASTM 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 EN10025-4 S420ML 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.

Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads. en10025-4 S420ML It is used in hot rolled or normalized state. In addition, Q345 steel is also widely used in construction, bridges, vehicles, ships, pressure vessels, etc.
