What are ABS Shipbuilding Steel Plates?

ABS Steel plates are types of structural steel plates for the Ocean project. ABS grade A is widely used in shipbuilding. ABS steel plate come many grades in ordinary-strength and two levels of higher-strength specifications. All of these steel plates have been engineered to be optimal long-lived shipbuilding steels. ABS does permit the use of other steels in shipbuilding. But discourages it, and requires more detailed engineering analysis. ABS Ship Class(American Bureau of Shipping). ABS Ship Class main steel grades include: ABS grade A, B, D, E, AH32, AH36, DH36, and so on.

• Available in four ordinary-strength grades: Grade A, Grade B, Grade D, and Grade E.
• Available in 12 higher-strength grades: AH36, DH36, EH36, and FH36. Other higher-strength grades may be special-ordered.

ABS 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.

ABS Grades A, B, D, E Shipbuilding Steel

Grade A Steel Plate

Designed for general-purpose shipbuilding with no specific impact toughness requirement at 20°C (4°F). Primarily used for bulkheads, frames, and deck plating in interior compartments and superstructures of ships operating in mild conditions.

Grade B Steel Plate

Requires 27 J impact toughness at 0°C (32°F). Suitable for shell plating, longitudinal bulkheads, and hatch coamings in cargo ships, ferries, and container ships operating in temperate environments.

Grade D Steel Plate

Requires 27 J impact toughness at -20°C (-4°F). Commonly used for hulls, keels, and deck structures in ice-class ships, trawlers, and offshore supply vessels operating in cold regions.

Grade E Steel Plate

Requires 27 J impact toughness at -40°C (-40°F). Ideal for icebreakers, polar research vessels, and offshore platforms operating in Arctic waters and extreme cold environments.
