The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel A514 Gr K alloy steel plate products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the A514 Gr K alloy steel plate market and has strong competitiveness.
EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll A514 Gr K alloy steel plate, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.
Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of A514 Gr K alloy steel plate, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong. Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.
When pouring the steel with high Mn content, some manganese oxide should be added in the initial slag in advance to prevent the occurrence of the above events. In order to prevent the longitudinal crack of wear-resistant steel plate, A514 Gr K alloy steel plate, some measures are often taken to reduce the content of P, S and Se in NM360 wear-resistant steel plate. Strictly control the liquid level fluctuation of the crystallizer; reasonably control the negative sliding time; try to increase the temperature difference of the water in the crystallizer as much as possible.
EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The A514 Gr K alloy steel plate, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
