Product Use

Medium and heavy 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 plates, boiler plates, pressure vessel plates, checker plates, automobile beam plates, certain parts of tractors and welding. components, etc. Application of medium and heavy plate: widely used to manufacture various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, patterned steel plates, Specific applications of automobile frame steel plates, certain parts of tractors and welded components.

Steel Plates For Bridges

Steel plates used for large railway bridges are required to withstand dynamic loads, shocks, vibrations, corrosion resistance, etc., such as: Q235q, Q345q, etc.

Shipbuilding Steel Plate

It is used to manufacture marine and inland ship hulls, requiring high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. Such as: A32, D32, A36, D36, etc. Boiler steel plate (boiler plate): It is used to manufacture various boilers and important accessories. Because boiler steel plate works under high pressure at medium temperature (below 350°C), in addition to high pressure, it is also subjected to impact, fatigue load and water and gas corrosion. , It is required to ensure a certain strength, but also have good welding and cold bending properties, such as: Q245R and so on.

Steel Plates For Pressure Vessels

It is mainly used for the manufacture of pressure vessels and other similar equipment for petroleum, chemical gas separation and gas storage and transportation. The general working pressure is from normal pressure to 320kg/cm2 or even 630kg/cm2, and the temperature is in the range of -20-450°C. In addition to a certain strength and good plasticity and toughness, the container steel plate must also have good cold bending and welding properties, such as: Q245R, Q345R, 14Cr1MoR, 15CrMoR, etc.

Steel For Automobile Frame

Manufacture automobile frames (longitudinal beams, cross beams), using low-alloy hot-rolled steel plates with a thickness of 2.5-12.0mm. Due to the complex shape of the automobile frame, in addition to high strength and cold bending performance, it also requires good stamping performance.
