ASME SA514 Grade B/ SA514 Gr.B high strength weldable steel plate steel plate

ASME SA514 Grade B high strength weldable steel plate is one of the high yield strength quenched and tempered alloy plates suitable for welding under the American Standard ASME SA514 / SA514M. It is also called SA514 Gr.B high strength weldable steel plate, which is one of the eight common specifications of ASME SA514 steel standard. The maximum thickness of ASME SA514 Grade B high strength weldable steel plate is 50mm.

ASME SA514 Grade B high strength weldable steel plate chemical composition:
