Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,ASTM A131 DH32 shipbuilding steel is not only the high tensile strength steel but also is the Hull structural steel. DH32 shipbuilding steel has good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and good welding properties.Shipbuilding steel grade DH32 is used for shipbuilding and oil platform purpose and they are approved by ABS,DNV,GL,BV,LR,NK,RINA and other classification societies.What's more, DH32 shipbuilding steel plate can be used in manufacturing the ship's hull structure whose weight is below 10000 tons.
DH32 Shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
