ABS DH32 shipbuilding steel plate chemical composition

DH32 steel is the common tensile strength shipbuilding steel, it has good toughness properties, higher strength, can be used in the ship's hull structure. In usual if ABS DH32 steel plate thickness above 40mm, mill request the normalized in hot rolled plate, if above 150mm thickness our mill also could use the Electro-slag remelting technical to do for our customers.
Specification of ABS DH32 steel plate:
Thickness: 5mm--640mm
Width: 1500mm--4000mm
Length: 3000mm -- 18500mm
