Generally, when we distinguish and judge whether it is a high-quality A709 Gr 100W bridge steel plate, automotive steel sheet manufacturer, the manufacturer's corporate brand and the reputation of the A709 Gr 100W bridge steel plate, automotive steel sheet are good proofs. We can check the sales of automotive steel sheets manufacturers and the comments of buyers on the products and so on aspects about the automotive steel sheet manufacturer. The ones with more sales and higher praise rate are naturally better manufacturers. These can be used as some reference opinions for us to choose automobile steel sheet manufacturers.
Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.
Tempering the important A709 Gr 100W bridge steel plate welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve A709 Gr 100W bridge steel plate strength, plasticity and toughness.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar.
