LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS AH36 Shipbuilding steel plate
Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,ASTM A131 AH36 steel plate, AH36 steel is a kind of steel for shipbuilding and platform. Shipbuilding steel plate AH36 is the high tensile strength steel. As a professional AH36 shipbuilding steel plate exporter, Bebon international can supply steel plate AH36. ASTM A 131 AH36 shipbuilding steel plates can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons.
AH36 shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
