DNV Grades A, B, D, E Shipbuilding Steel Plate Supplier and Manufacturer

DNV Grades A, B, D, and E are ordinary-strength structural steels with a minimum specified yield strength of 34 ksi and specified minimum Charpy V-notch impact toughness properties.

Applications

Typical applications include shipbuilding and mobile offshore drilling units and structures.

DNV Grade A shipbuilding steel plate is a common strength ship plate which owned the minimum yield strength at 235 Mpa.When supplying steel plate DNV Grade A,hot rolled or TMCP is Ok for these shipbuilding steel plates and sheets.

DNV Grade B,NV B,DNV B steel plate mainly used to build vessels that sail in common ocean waters at about zero centigrade. For the thickness above 40mm,our engineers suggest that customers accept doing Normalized heat treatment for DNV Grade B steel plates.

DNV C Steel Plate refers to marine-grade structural steel certified by DNV (Det Norske Veritas), a classification society, with ‘C’ often indicating a common grade like DNV Grade C or potentially related to carbon content in general steel types, used for shipbuilding, offshore structures, and bridges, offering good strength and toughness, especially at low temperatures, often categorized with A, B, D, E grades for varying toughness requirements, while ‘C’ in other contexts might mean medium carbon steel.

DNV Grade D steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels,ship body construction.Normally when rolling,Air rolled and Control Rolled is ok for ship plate DNV Grade D with the thickness equal and belows 40 Millimeters,and for thickness above 40mm,the heat treatment shall be Normalised or TMCP,these two technical treatment would improve steel strength in yield and tensile points for shipbuilding steel plate DNV Grade D.
