AN IMPROVED HIGH YIELD STRENGTH STEEL FOR SHIPBUILDING

High strength ferritic steels have been successfully used for construction of pipelines and offshore oil drilling platforms for several years. One of these steels, HSLA-80, a derivative of ASTM A710 Grade A material, is now being specified for the construction of U.S. Navy ships as a replacement for HY-80 the high yield steel previously used in these ships. Although both materials have yield strengths of 80,000 psi (552 MPa) the improved weldability and fabrication ease of HSLA-80 can provide substantial savings in construction costs. Accordingly, an extensive welding engineering programme has been undertaken to characterise the properties and determine the process conditions for successful welding of HSLA-80. The programme, summarised in this paper, includes weldability studies, welding procedure qualifications and field weldment inspections.
