DH36 Shipbuilding Steel Plate with 355MPa Yield Strength and Impact Tested Hull Structural Steel Plate

For ship hulls and offshore structures that must withstand heavy loads, low temperatures, and harsh marine conditions, DH36 shipbuilding steel plate is a trusted high-strength structural material. Manufactured to ASTM A131 and GB 712 standards, DH36 offers a minimum yield strength of 355 MPa together with excellent toughness at low temperature (impact tested at −20 °C), making it a standard choice for hull girders, decks, and marine engineering structures worldwide.

DH36 belongs to the family of higher-strength hull structural steels. In the designation "DH36", the letter D indicates the impact toughness tested at −20 °C, H refers to higher strength, and 36 denotes a minimum yield strength of 36 kgf/mm² (about 355 MPa). The plate is fully killed and fine-grain treated, offering a good balance of strength, weldability, and notch toughness. DH36 is widely certified by the major classification societies such as ABS, DNV, LR, BV, CCS, and NK.
