To eliminate scrap for hardness of parts of sintered 30NM steel after hardening and low-temperature tempering of them with possible variations in carbon content of the material, the following conditions are necessary: nondestructive testing and inspection of parts after sintering for carbon content by the method of measurement of their coercive force. If necessary measurement of the density of the parts after sintering using the saturation magnetization is possible; nondestructive testing and inspection of the hardened parts based on hardness by measurement of their coercive force. In some cases prediction of the hardness after hardening and low-temperature tempering using the results of measurement of the coercive force of hardened parts is possible. |
