General Info About ABS A & B

These steel grades 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.

More Details About ABS A & B

  • Advantages/Disadvantages

    These steel plate grades are specifically for shipbuilding.

  • Industries

    These structural grades of steel plate are only used in the shipbuilding industry.

  • Applications

    These structural steels are only used in the shipbuilding industry. Some of their common applications include barges, ship construction, and marine equipment.

Frequently Asked Questions About ABS A/ABS B

  • What does ABS stand for?


    It 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?


    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?


    All ordinary-strength steels of this type have a yield point at 34,000 psi (235 MPa), but there are two exceptions. First, type A with 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?


    All ordinary-strength steels of this type have an ultimate tensile strength of 58,000 – 71,000 psi (400 -490 MPa), but there are exceptions. The first exception is for type 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).
