LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,EH32 Shipbuilding steel plate

Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,The EH32 shipbuilding steel plate is the mainly kinds of steel for shipbuilding and oil platform, the shipbuilding grade EH32 can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons.  Shipbuilding grade EH32  is the high tensile strength steel,  EH32 steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.

EH32 shipbuilding steel plate specification:
Thickness: 4mm to 260mm, Width: 1200mm to 4000mm, Length: 3000mm to 18000mm.
