Carbon steel plates are produced with thickness up to 3mm-350mm. We can supply A709 Gr 50S bridge steel plate, hot rolled plate, sheets, and angles. Carbon steel plates tolerance: Thickness, width and length tolerances for steel plates are in accordance with ASTM A6. Our carbon steel plate tolerances or better are available for temper leveled plates. Flatness capabilities are determined bythe processing line and the minimum yield strength of the material.
The addition of Ca element in steel such as A709 Gr 50S bridge steel plate can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as A709 Gr 50S bridge steel plate, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
