DNV Grade A shipbuilding steel

DNV grade A steel is a kind of hot rolled general tensile strength steel. DNV steels come 4 grades in ordinary-strength steel for shipbuilding and grade A is the lowest one of them.

DNV Grade A Steel Grade Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.

The DNV A grade steel plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). All the DNV/A shipbuilding Steel offered by Katalor Industry can be certificated by Det Norske Veritas (DNV).

DNV Grade A shipbuilding Steel Application:
DNV A grades of steel plate are almost exclusively used in the Shipbuilding Industry for the construction of structural parts of ships, barges and marine equipment. DNV A Shipbuilding steel plates also can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components.
