ASTM A514 Grade Q/ A514 Gr.Q high strength weldable steel plate steel plate

ASTM A514 Grade Q/ A514 Gr.Q high strength weldable steel plate is high strength weldable steel plate for quenching and tempering under the ASTM A514 / A514M standard. The main purpose is to use under high tensile, high yield sites. The engineering car lifting gear and the rack used in the offshore platform generally use ASTM A514 Grade Q/ A514 Gr.Q high strength weldable steel plate.
