LR A steel and Grade A/Grade B/Grade D/Grade E shipbuilding plate

LR A steel is a kind of hot rolled general tensile strength steel. General-strength LR shipbuilding steel comes in 12 grades of 3 strengths,Grade A is one of the grades. The LR grade A steel plates have yield strength of 235 MPa, and ultimate tensile strength of 400-520 MPa. All the LRA shipbuilding Steel offered by Gnee can be certificated by Lloyd’s Register of Shipping (LR).

Grade A steel is the impact force subjected to 20℃
Grade B steel impact force at 0℃
Grade D steel impact force at -20℃
Grade E steel impact force at -40℃

Processing for Different Grades
Grade D, E (DH32, DH36, EH 32, EH 36)
Grade D and E series (inlcuding AH32/36, DH32, DH36, EH32, EH36) shipbuilding steel plates require good low temperature toughness and good welding performance. The production high-strength shipbuilding steel plate needs to be normalized by means of controlled rolling and controlled cooling or heat treatment processes with more complete equipment.

At the same time, the internal steel purity of the supplied billets is required to be high, especially the content of S, P, N, 0 and H in the steel should be strictly controlled.

We can supply the LR A steel and Grade A, Grade B, Grade D, Grade E. Such as DH32, DH36, EH 32, EH 36. if you have any demand, please contact us freely. We can produce the steel size with your requirements.
