LR AH32 steel is a kind of hot rolled high tensile strength steel. As with other grades of steel, LR AH32 steel has a specific gravity of 7.8. Higher-strength LR shipbuilding steel comes in 12 grades of 3 strengths, AH32 is one of the grades. The LR AH 32 grade steel plates have yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-590 MPa). All the LR AH32 shipbuilding Steel offered by Katalor Industry can be certificated by Lloyd’s Register of Shipping (LR).
LR AH32 Shipbuilding steel plates are mainly used for making the hull of ship building and ship repairing, the offshore oil drilling platform, the platform pipe joints and other components. LR AH32 Shipbuilding steel plates also can be used for producing container and bulk cargo vessels
