HIGH TENSILE STEEL IN SHIPBUILDING II

A joint research project organized by four shipyards, three steelworks, one welding-material firm and the Swedish Ship Research Foundation (SSF). In order to evaluate steels with yield strength above those used prior to 1972 and study the precautions that these may make necessary if used for building ships as well as the risks which may be encountered in service, the parties involved in this investigation agreed to arrange a joint research project. The aim of the project was to supply the shipyards with necessary data for their design departments as well as give the production departments a good understanding of the advantages and disadvantages to be reckoned with, if the higher yield point steels are used for welded ship hull constructions. Fundamental and advanced strength investigations of base material and welded joints have been carried out, as well as studies on shop handling consequences and the influences of the environment on the welding results. The steels chosen for this study have a yield point of about 350, 400 and 500 Netwons/squared mm, i.e. 36, 40 and 50 km/squared mm. Special regard has been taken to their use in welded ship structures.
