Specification :
Shipbuilding steel material can be divided into two different parts according to it's tensile strength, that is general strength shipbuilding steel and high strength shipbuilding steel. A, B, D, E, these grades belongs to general strength shipbuilding steel material, AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, EH36, FH40, belongs to high strength steel material .

Shipbuilding steel grade , AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, EH36, FH40, are the high tensile strength steel.They are the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.This kind of steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons.
