The final purpose of this study is to clarify corrosion fatigue behaviour of steel plates and welded joints. In this report, the effect of alloyed elements on corrosion fatigue of steel plate was described. Results obtained are as follows : 1) In air, fatigue strength of low carbon steel alloyed by phosphor was increased than that of low carbon Si-Mn steel, but no effect of titanium, copper and chromium alloying was observed on the fatigue strength. 2) The effect of alloyed elements on the increment of corrosion fatigue strength in 3% NaCl aq. solution was observed not at all. Conversely, corrosion fatigue strength of titanium-alloyed low carbon steel was very low value. 3) Fatigue strength in air increased with the increment of the tensile strength of steel plates, but corrosion fatigue strength was not varied in spite of increment of the tensile strength. 4) Corrosion fatigue test in 3% NaCl aq. solution showed no endurance limit.
