LR DH32 steel plate/sheet for shipbuilding is not only high-tensile-strength steel but also is the Hull structural steel with good toughness properties, higher strength, strong corrosion-resistance,the processing properties,and good welding properties. The LR DH32 grade steel plates have a yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000-85,000 psi (440-590 MPa).

LR DH32 shipbuilding steel Application range

LR DH32 steel plate/sheet is used for shipbuilding and oil platform purpose and they are approved by ABS, DNV, GL, BV, LR, NK, RINA and other classification societies. What’s more, DH32 shipbuilding steel plate can be used in manufacturing the ship’s hull structure whose weight is below 10000 tons.
