In the former report, the two step forging process utilizing divided flow was concluded to be useful for the precision cold die forging of a spur gear under a low working pressure. This conclusion, however, was obtained by adopting the test material of aluminium A 1100-O. In this report, the application to a steel product and several constructions of the two step method are examined in order to clarify the usefulness of this process more universally. Through these examinations, it is concluded that the maximum fractional working pressure required for the filling up of a spur gear with a steel S10C is less than 3.0 and the filling up behavior of S10C is almost the same as that of A 1100-O. When the two step process constructed with mandrel movement is carried out by a double action press, it becomes more effective for decreasing the working pressure and saving the material. Thus, it is confirmed that the process utilizing divided flow can be used practically.
