Abstract
This study examines the corrosion fatigue properties in weld metal and heat-affected zone of butt welded joints of high strength steels in order to investigate reduction of their respective fatigue strengths in saline water. The tested materials are two kinds of 50 kg/mm2 class high strength steel (A-steel is ordinary steel, B-steel atmosphere-resistance steel) and 60 kg/mm2 class high strength steel (C-steel, quenched and tempered steel).<BR>From the test results, it is clear that the fatigue strength in 3% saline water on the weldment of Asteel is lower in the heat-affected zone than in the base metal while it is almost even in each zone of the weldment of B- or C-steel. The lower fatigue strength in 35/a saline water in the heat-affected zone of A-steel is due to the high sensitivity of the notches such as corrosion pits in comparison with other steels.
