ABS Grade A B D E shipbuilding steel plate
The general grades A, B, D, and E are distinguished according to the impact temperature of the steel. The impact values of all grades of steel are the same.
According to its yield strength, shipbuilding plate of can be divided into below grades:
Grade A steel is the impact force subjected to normal temperature (20 ° C).
Grade B steel impact force at 0 °C.
Grade D steel impact force at -20 °C.
Grade E steel impact force at -40 °C.
