LR Grade B shipbuilding steel plate is a kind of hot rolled general tensile strength steel. LR Grade B shipbuilding steel plate have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). LR steels come 4 grades in ordinary-strength steel for LR Grade B shipbuilding steel plate is one of them.
LR Grade B shipbuilding steel plate can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components. LR Grade B shipbuilding steel plates are almost exclusively used in the Shipbuilding Industry for the construction of structural parts of ships, barges and marine equipment.
