Two steel ingots were taken from each of the three kinds of steel melts of the basic open hearth furnace, to investigate the mechanical properties of axles subjected to different methods of working. Comparative experiments were made on the three kinds of axles made from the three kinds of steel melts such as axles directly forged from the steel billets, that with the central and neck parts forged from the steel bar and that as directly machined from the bar. It was found from the result that there is no remarkable difference among the mechanical properties of axles as far as an excellent steel ingots from the one and the same steel melts and as far as there is little difference in the temperature of heat treatment. Therefore it become distinct that any method of working axles will reveal the same characteristics as far as an excellent steel ingots are used and as far as the last stage of heat treatment is performed suitably.
