ABS grade E shipbuilding steel plate

ABS Grade E shipbuilding steel plate refers to a specific grade of marine-grade steel approved by the American Bureau of Shipping (ABS).

Key characteristics and specifications of ABS Grade E shipbuilding steel plate include:

Chemical Composition (in weight percentage) of ABS grade E shipbuilding steel plate:

Carbon (C): ≤0.18%

Manganese (Mn): 0.70-1.20%

Silicon (Si): ≤0.50%

Phosphorus (P): ≤0.035%

Sulfur (S): ≤0.035%

Nickel (Ni): ≤0.40%

Chromium (Cr): ≤0.35%

Copper (Cu): ≤0.35%

Aluminum (Al): ≤0.015%

Mechanical Properties of ABS grade E shipbuilding steel plate:

Tensile Strength: 58,000-75,500 psi (400-520 MPa)

Yield Strength: 34,800 psi (240 MPa) minimum

Elongation: 22% minimum in 8 inches and 26% minimum in 2 inches

Heat Treatment:

ABS Grade E shipbuilding steel plate is typically thermomechanically controlled processed (TMCP) to improve its toughness, grain refinement, and weldability.

Applications of ABS grade E shipbuilding steel plate:

ABS Grade E shipbuilding steel plates are primarily used for constructing ships and marine structures. They are designed to withstand high-impact loading conditions and harsh marine environments, offering excellent strength, toughness, and corrosion resistance.

Certification:

ABS Grade E shipbuilding steel plate is certified by the American Bureau of Shipping, which ensures compliance with stringent quality standards and regulations for shipbuilding materials.

Weldability and Fabrication:

ABS Grade E steel plate exhibits good weldability, allowing for efficient fabrication and assembly processes. It can be easily cut, formed, and welded to meet specific project requirements.

Additional Testing and Requirements:

The steel plate may undergo various additional tests, including ultrasonic examination, Charpy V-notch impact test, and notch toughness testing, to ensure compliance with specified standards and project specifications.

ABS Grade E shipbuilding steel plate is just one specific grade within the ABS classification society standards. Various other grades (e.g., A, B, D) are also available, each tailored for different applications and strength requirements in shipbuilding and offshore structures.
