ST37 Cold Rolled Alloy Steel Plate

 From a commercial point of view, the lower the amount of alloy, the lower the cost, which is in line with the principle of economical practicality. The groove toughness, yield ratio, weldability and corrosion resistance of high-strength alloy steel are better than those of ordinary steel, and the processing method is the same as that of ordinary carbon steel. The development of microalloyed steels began in the late 1950s. With the wide application of welded structures after...
