ASME SA514 Grade B material is a quenched and tempered alloy steel plate for structural applications requiring high yield strength combined with good formability and toughness. A514 Grade B plae has a minimum yield strength of 100 ksi [690 MPa] and may be ordered with supplemental Charpy. As a supplier of A514 Grade B steel plates, our A514 Grade B plate can be supplied with thickness up to 150mm.
V-notch impact test requirements.

ASME SA514 Grade B steel formability
ASME SA514 Grade B carbon steel plate exhibits good cold forming characteristics. Shear burrs and heat-affected zones of thermal cut edges on or near the bend axis as well as sharp corners on edges and on gas cut or punched holes located on or adjacent to the bend axis should be removed by grinding prior cold forming.
ASME SA514 Grade B steel application
ASME SA514 Grade B carbon steel plates can used for welded bridges and other structures like transport trailers, construction equipment, crane booms, mobile man-lifts, agricultural equipment, heavy vehicle frames and chassis, and welded bridge structural members.
