LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, Grade E Shipbuilding steel plate
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.
