Introduction to ASTM A514 steel plate
ASTM A514 steel plate is a high-strength weldable steel plate that has been quenched and tempered, and it follows the ASTM standard. The following is a detailed introduction to ASTM A514 steel plate:
Weldability: The steel plate has good welding performance and can be connected through appropriate welding processes to meet the needs of complex structures.
Diverse levels: There are eight different levels under the ASTM A514 standard, including A514 GrA, A514GrB, A514GrE, A514GrF, A514GrH, A514GrP, A514GrQ, A514Gr.S. Different levels of steel plates vary in thickness, chemical composition and performance.
