General Info About ABS A & B

  • Advantages/Disadvantages

    ABS A and ABS B are defined as ordinary strength and these grades are certified by the American Bureau of Shipping (ABS) so that they can be used in shipbuilding.

  • Industries

    ABS A & B are structural grades of steel plate that are only used in the shipbuilding industry.

  • Applications

    ABS A & B are only used in the shipbuilding industry and therefore common applications include barges, ship construction, and marine equipment.

Frequently Asked Questions About ABS A/ABS B

  • What does ABS stand for?

    ANSWER:

    ABS stands for American Bureau of Shipping and indicates that the grade was certified by the Bureau.

  • What is the difference between ABS A/B and ABS AH36/DH36/EH36/FH36?

    ANSWER:

    ABS ordinary-strength steel comes in a various number of grades, including A, B, D, E, and F. Each of these grades have different alloy chemical ingredients and a different fracture toughness.

  • What is the yield point for ordinary-strength ABS steels?

    ANSWER:

    All ordinary-strength ABS steels have a yield point at 34,000 psi (235 MPa), but there are two exceptions. First, ABS A with a thicknesses greater than 1 inch have a yield point of 32,000 psi (225 MPa) and, second, cold flange rolled sections have a yield point of 30,000 psi (205 MPa).

  • What is the ultimate tensile strength of ordinary-strength ABS steels?

    ANSWER:

    All ordinary-strength ABS steels have an ultimate tensile strength of 58,000 – 71,000 psi (400 -490 MPa), but there are exceptions. The first one is ABS A shapes and bars with tensile strengths of 58,000 – 80,00 psi (400 – 550 MPa). Second are cold flanged sections with tensile strengths of 55,000 – 65,000 psi (380 – 450 MPa).
