    General Product Description

    ASTM A945 GRADE 65 IS AVAILABLE BY INQUIRY ONLY.

    ASTM A945 Grade 65 steel plate is a high-strength low-alloy structural steel with improved weldability, formability, and toughness for use in the construction of naval ships. ASTM allows the manufacturer the option to provide plates in thicknesses of 1.25 inches and less in the delivery conditions of as-rolled, normalized, or quenched and tempered. Plates greater than 1.25 inches in thickness must be supplied in the quenched and tempered condition. SSAB's First Article Inspection report is available upon request.

            1) For plates wider than 24 in. the elongation requirement is reduced two percentage points. See Tension Tests section of ASTM A370 for elongation requirement adjustments.

            Impact Properties

            Charpy V-Notch impact testing in accordance with ASTM A673. Please inquire for orders requiring more stringent CVN impact testing.
