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(Z23/Z35), B(Z23/Z35), D(Z23/Z35), E(Z23/Z35).these grades belongs to generalstrength shipbuilding steel material, AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, EH36, FH40, API 2HCR50 belongs to high strength steel material .

A(Z23/Z35), B(Z23/Z35), D(Z23/Z35), E(Z23/Z35)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 ship's hull structure whose weight is below 10000 tons,and usually do navigation around coastal and river area.
