MODIFYING THE MICROSTRUCTURE AND PROPERTY OF

quenching process of 30CrMnSi steel is holding at 870℃ by oil cooling. Tempered sorbite can be obtained after conventional quenching and subsequent tempering. During the practical process, brittle fracture sometimes appears in the conventional heating treated 30CrMnSi steel product due to the poor ductility. It is an effective

A Study of the Effect of Two Stage Tempering on Mechanical

The repeated quenching and first tempering in experiment D result in a lower level of mechanical properties. The second austenitizing after quenching and tempering naturally require less time than the austenitizing of a perlitic structure . In addition, air heating of the steel causes its decarburization.
