A longer term objective is to facilitate the introduction to the shipbuilding industry of the new high strength steels processed by advanced on-line processing techniques with toughness and weldability properties beyond those currently available. The study has provided a preliminary characterization of newly developed steels with yield strengths varying from 65 ksi to 120 ksi. On the basis of the preliminary data obtained. it appears that by use of advanced metallurgical processes. high strength steels can be produced which provide improved toughness and weldability; the alloying elements required for such steels could be substantially lower than that required for conventionally processed quenched and tempered steels of the same strength and toughness levels.
