Abstract��Through the comparison of austenite grain size of 60Si2CrVAT spring steel at different depths obtained with direct quenching methods and oxidation methods, the error results of austenite grain size of 60Si2CrVAT spring steel via oxidation test was analysized. It is can conclude that, for measuring the austenite grain size of 60Si2CrVAT spring steel by oxidation method it is the most important to control the grinding depth of the test surface as follows: to slightly remove iron oxide scale of test surface by grinding and then polish and directly observe the surface, or to etch in 15% hydrochloric acid alcohol solution in order to make the grain boundary more clear and then observe the surface.
