ABS marine shipbuilding steel plate

The American Bureau of Shipping(ABS) is a maritime classification society established in 1862. Its primary responsibility of ABS is to verify that ABS-classed ships and marine structures comply with the established rules for design,construction and periodic survey.

ABS marine shipbuilding steel plate is structural steel used for different building applications. This type of steel comes in many grades to provide different specifications that are applicable to shipbuilding.

The different grades are certified to be used in shipbuilding capacities for structural parts of ships, barges, and other marine equipment. It includes DNV, GL, ABS, NK, LR,BV,CCSA,RINA,GL etc; 9 largest classification societies.

High-strength hull structure steels are classified according to their minimum yield strength, and each strength grade is classified into A, D, E, and F4 according to their impact toughness.

The ABS marine shipbuilding steel plate is divided into four grades A, B, C, and D. The yield strength of these four grades of steel (not less than 235N/mm^2) and the tensile strength (400~520N/mm^2) are the same. , but the impact energy at different temperatures is different;
