| Abstract: | The effect of austenitizing conditions on the hardening results of YK steel used for wood-chip cutter is investigated. The influence of austenitizing temperature and time on the austenite grain size, the relationships between austenitization and quenching hardness and the effect of the retained austenite on tempering transformation are discussed. The result shows that the performance of the new type steel, according to the chemical compositions and the service conditions of machine knives, can be improved by means of proper austenitizing and its secondary hardening. |
