    General Product Description

    ABS Grades A, B, D, and E Z25 are "Z" quality, ordinary-strength structural steels with a minimum specified yield strength of 34 ksi and specified minimum Charpy V-notch impact toughness properties. The Z25 quality steel has a minimum specified average value for reduction of area in through-thickness tensile testing of 25%.

    Applications

    Typical applications include shipbuilding and mobile offshore drilling units and structural details for which greater resistance to lamellar tearing is desired.

        Mechanical Properties

        Tensile testing is performed in the transverse direction. When "Z" quality steel is specified, through-thickness tension testing is performed in accordance with ABS Rules.

                1) Specimen orientation at the option of the manufacturer unless otherwise specified in the order.

                No more than one value below the specified miniminum average energy but no less than 70% of the specfied minimum average energy value.

                Impact tests not required for Grade A if produced using fine grain practice and normalized.
