Abstract:
In order to clarify influences of nonmetallic inclusion on fatigue strength of carburized and shot peened gear steel, bending fatigue tests and pitting fatigue tests were
carried out on a clean steel with oxyeng content of 9ppm and a conventional steel with oxygen content of 20ppm, respectively. As a result, it was revealed that the clean
steel showed higher fatigue strength than the conventional steel in both of the fatigue tests. The test result was discussed from a view point of the size and the density
of nonmetallic inclusion.
