Recently, with increasing need of high working stress level of steels, metallurgists have had another look at martensite and found that some heat-treated medium carbon steels can have considerable toughness with ultra high strength. In these cases, it is important to get the correlations between the fatigue strength and well known low temperature temper brittleness of steels or so called “A-brittleness”. From these stand points, this study was carried out to get an account of the influence of tempering temperature on the fatigue properties of a low carbon martensite steel. Both unnotched and notched bars were tested at room temperature with “Amsler High Frequency Vibrophore” which operated at frequency of 110±10 c.p.s. under alternating tension-compression load. In addition, tensile, hardness and impact properties were tested. The results obtained in this paper are as follows: When unnotched bars were used, the minimum fatigue strength was obtained by tempering at about 300°C. Namely, the existence of a correlation between “A-brittleness” and fatigue strength of tempered steels was confirmed. However, when notched bars were used, the substantial effects of temperings temperatures on endurance limit could not be found.
