    General Product Description

    ABS Grades AH32, DH32, and EH32 Z35 are "Z" quality, higher-strength structural steels with a minimum specified yield strength of 46 ksi and specified minimum Charpy V-notch impact toughness properties. The Z35 quality steel has a minimum specified average value for reduction of area in through- thickness tensile testing of 35%.

    Applications

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

        Width: Please inquire for plate widths less than 72 in. and inquire plate product over 120 in.

        Thickness: Inquire for plate thickness less than 0.75 in.

        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.
