EFFECT OF SULFUR CONTENT ON CORROSION FATIGUE PROPERTIES

Fatigue tests have been performed in both air and dripping corrosive liquids with pH7 and pH13 under rotating bending load at the cyclic frequency of 300 rpm. The materials used in this test are four kinds of normalised and tempered (NT) steels and four kinds of quenched and tempered (QT) ones whose sulphur content whose sulphur content changes from 0.001 to 0.050%, respectively. Corrosion fatigue strength has been evaluated from the points of on corrosive liquids and sulphur contents. In addition, fractographic observation has been discussed. Then, it is confirmed that the fatigue strength in corrosive environments is not so dependent on sulphur contents, though it becomes between 1/3 to 1/6 times of that on air and the number of pits and cracks increase with the increase the sulphur contents.
