ABS Grade A general strength Shipbuilding steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels, ship body construction. Normally when rolling, Air rolled and Control Rolled is ok for ABS Grade A ship plate with the thickness equal and below 40 Millimeters, and for thickness above 40mm, the heat treatment shall be Normalized or TMCP, these two technical treatment would improve steel strength in yield and tensile points.
Technical Details:
Heat Treatment: Normalized, Quenched, Tempered, Impact Test, (Optional if not provided in rules)
