LR FH40 shipbuilding steel plate is a kind of hot rolled high tensile strength steel. The LR shipbuilding steel plates have yield strength of 56,500 psi (390 MPa), and ultimate tensile strength of 74,000 - 94,500 psi (510-650 MPa). LR FH40 steel can achieve the impact toughness at Celsius degree -60°. All the LR FH40 shipbuilding steel plate offered by Katalor Industry can be certificated by Lloyd’s Register of Shipping (LR).
LR FH40 shipbuilding steel plate are mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components.
