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 KUNFENG Industry can be certificated by Lloyd’s Register of Shipping (LR).
