ASTM A514 Grade P high strength weldable steel plate is short for A514 Gr.P high strength weldable steel plate, which has high strength. Even at extremely low temperatures, A514 Gr.P high strength weldable steel plate can still maintain its mechanical properties. Good anti fatigue properties, high toughness and low brittle transition temperature, good cold forming and welding properties, good corrosion resistance and certain wear resistance etc. features bring ASTM A514 Grade P high strength weldable steel plate wide application.
