Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,ASTM A131 Grade E shipbuilding steel is not only the common tensile strength steel but also is the Hull structural steel. Grade E shipbuilding steel has good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and good welding properties. Shipbuilding steel grade E 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,the A shipbuilding steel E 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.
Grade E shipbuilding steel plate specification:
Thickness: 6mm-200mm, Width: 1500mm-4000mm, Length: 6000mm-180000mm
