A recent advent in ship construction is the use of high-strength low-alloy steels with 100,000-psi yield strengths for ship hull structural elements, making unique design concepts possible. This application is a significant step, but the material's behavior needs to be further defined. For the benefit of the owners, designers, and fabricators, a project was initiated by the Ship Structure Committee to establish which mechanical properties should be used as criteria for judging performance, to evaluate large-scale weldments to determine the suitability of these criteria, and to select small-scale laboratory tests that correlate with the large-scale tests. A survey of shipyards and ship repairers revealed that these newer materials are being used only in critical strength elements of ship hulls. Welding procedures are qualified by explosion bulge tests to define safe operating temperature limits. (Author)
