What is EN S420M steel plate equivalent ASTM steel

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of EN S420M steel plate, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
