In this thesis, series of lowcarboncaststeel shot were successfully obtained by medium-frequency melting and centrifugal atomization technologies and temper were performed.
Experiments were carried out upon the hardening and toughening, wear resistance and abrasive behaviour of the low alloyed high carbon wear resistant caststeel.
