Short answer: Shipbuilding steel is a normalized or TMCP high-strength structural plate graded by charpy impact temperature – AH36, DH36 and EH36 – for hulls and offshore structures, supplied from the basis in our Metal for Marine Guide and the stock forms in our Steel Plate Buyers Guide.
At a Glance
What Shipbuilding Steel Is
Shipbuilding steel is a high-strength structural plate made for hulls, decks and offshore structures. Grades AH36, DH36 and EH36 share a 355 MPa yield but differ by the temperature at which they keep impact toughness. The marine context is in our Metal for Marine Guide.
Grade Selection by Temperature
AH36 is for ambient service, DH36 keeps toughness at low temperature, and EH36 is for arctic and deep-cold duty. The comparison below shows the shared strength with different toughness levels.
| Grade | Yield | Use |
|---|---|---|
| AH36 | 355 MPa | Hull structures |
| DH36 | 355 MPa | Low-temp service |
| EH36 | 355 MPa | Arctic service |
Testing and Certification
Marine plate is supplied with charpy impact at the design temperature and classification-society approvals, verified by the method in our Quality Inspection Guide and documents in our Mill Test Certificate Guide.
Soudage et fabrication
Hull fabrication needs qualified welding procedures; the basis is in our Metal Welding Guide and corrosion protection in our Metal Surface Treatment Guide.
Specifying and Sourcing
