ASTM A572 Gr.42 Alloy Steel Sheet

  Since it is a non-heat-treated type, its carbon content is generally not higher than 0.15%; due to the low content of alloying elements, they can mostly dissolve in fertilizer iron. 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...
