Plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc.It can also be used to manufacture various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, etc.Steel plates for pressure vessels: mainly used to manufacture pressure vessels and other similar equipment for petroleum and chemical gas separation and gas storage and transportation. The general working pressure is from normal pressure to 320kg/cm2 or even to 630kg/cm2, and the temperature is between -20-450°C. Working within the range requires the container steel plate to have a certain strength, good plasticity and toughness, but also good cold bending and welding performance.
