AN APPRAISAL OF THE PROPERTIES AND METHODS OF PRODUCTION OF LAMINATED OR COMPOSITE SHIP STEEL PLATE. SPECIAL REPORT

The conclusions and opinions of the Committee on Ship Steel with regard to the use of laminated or composite steels in ships can be summarized as follows: (1) The available data indicate that plates containing layers of weakness in the thickness direction are no more effective in inhibiting crack initiation than similar homogenous materials; (2) Mild steels clad with notch tough surface layers on one or both sides have lower transition temperatures than the unclad base material, but clad materials are expensive to produce and frequently require the use of strategically critical materials. Moreover, there are homogenous steels of sufficient notch toughness available that can be produced on a tonnage basis at a much lower cost than clad steels and (3) Considerable promise in inhibiting crack initiation or propagation has been shown in preliminary tests of properly applied notch tough weld beads and strakes of notch tough plating. Further exploration of these possibilities is currently underway.
