S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. SA633 Gr D carbon steel plate sheet, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.

SA633 Gr D carbon steel plate sheet, Q390B steel plate generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, The scrap steel is added to the furnace along with the charge and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it is cast immediately. Rare earth elements are added to the steel, the Q390B steel plate is purified, and the content of inclusions is greatly reduced.
