China HongKun offers different grades that are certified by ABS (American Bureau of Shipbuilding) and represents the Higher Strength Group of ABS steel plate grades AH36, DH36 and EH36.
Like ABS steel plate grade A & grade B, these grades of steel plate are almost exclusively utilized in the shipbuilding industry for the construction of structural parts of ships, barges and marine equipment.
ABS Grade A shipbuilding Steel Description:
ABS grade A steel is a kind of hot rolled general tensile strength steel. ABS steels come 4 grades in ordinary-strength steel for shipbuilding and grade A is the lowest one of them. The ABS 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 ABS/A shipbuilding Steel offered by GNEE can be certificated by American Bureau of Shipping(ABS).
ABS Grade A shipbuilding Steel Application:
ABS 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. ABS A Shipbuilding steel plates also can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components.
ABS Grade A Steel Grade Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm,
Length: 3000mm to 18000mm.
