Surface Decarburization Behavior of Spring Steel 60Si2MnA under A_C1 Temperature and in Temperature Range A_C3-G

Abstract:

Surface decarburization of spring steel 60Si2MnA heated under A_C1 temperature and in temperature range of A_C3-G was investigated. The results show that under the A_C1 temperature, pearlite spheroidization and surface decarburization were carried out simultaneously and had a mutual promotion relationship. In the temperature range of A_C3-G, decarburized layer consisted of complete and partial decarburization, and the complete decarburized depth increased but the partial decarburized depth just a small change with the increase of heating time. Besides, when heating temperature was 790 °C, functional relation between the total decarburized depth, the complete decarburized depth and the heating time follows the formula of and , respectively.
