Wear resistance of carburizing and induction hardening specimens

The high wear resistance of carburized steel is due to the high carbon content of the surface layer. When the carbon steel w(C) is less than 0.43%, the carburized part has an advantage in wear resistance, and when w(C) When it is higher than 0.45%, the wear resistance of the induction hardened parts is improved. This is the conclusion that TH HACAHOBA has drawn based on the field test of the track pin. Therefore, the tractor track pin is replaced by a new induction hardening process of 50 steel. . The comparison of the wear resistance of different w(C) steels after induction quenching illustrates the influence of steel composition. The data in the table proves that T7 steel has the smallest amount of wear, and its carbon content and hardness are also the highest; 45 steel and 50Mn have similar wear resistance; 45Cr steel has a wear resistance between T7 steel and 50Mn steel, indicating that the steel is in Containing Ming can improve abrasion resistance.
