DNV AH36 Shipbuilding Steel

Grade DNV AH36 marine steel, NV A36 material is a hull structural steel. DNV AH36 shipbuilding steel is mainly used for higher strength ships and ocean engineering structural steel. In the standard ASTM A131/A131M, offshore steel grade ASTM A131 AH36 is the best equivalent steel grade with DNV AH36. Shanghai Katalor can offer DNV AH36 Shipbuilding Steel, NVA36 marine steel with various sizes, shapes and large inventory. Our DNV AH36 shipbuilding Steel plates, sheets, bars, angle steel, bulb flats offered by Katalor Industry can be certificated by Det Norske Veritas (DNV).
