Physicomechanical properties of powdered 30N2M steel after carburization
The effect of the carburization time (0.5–2.0 h) on the magnetic and electric properties, the structural state, and the hardness of 30N2M steel was studied. The mechanical and physical properties of carburized steel are compared to those of conventionally sintered steel. The problems of magnetic structural analysis of carburized steel are discussed. It is concluded that in order to determine indirectly the hardness of articles made of powdered steel it is necessary to construct calibration curves of HB(Hc) for carburized and sintered 30N2M steel.
