ASTM A514 Grade B alloy steel plate has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming property and welding performance, good corrosion resistance and wear resistance. A514 Grade B alloy steel plates are mainly used in places requiring high tensile strength and high yield.
