ASTM A633 Grade D is made by adding a small amount of alloying elements on the basis of carbon structural steel. ASTM A633 Grade D has good welding performance, plasticity, toughness and processing properties, good corrosion resistance, higher strength and lower critical transition temperature of cold brittleness. ASTM A633 Grade D is suitable for building bridges, ships, vehicles, railways, automobiles, tractors, large steel structures and large military projects.
