ABSTRACT:
Disclosed is a refined and alloyed martensite-free cast steel abrasive material and method of making the same. The abrasive material is either shot or grit and has a composition which includes carbon in about the range of 0.60 to 1.20 percent by weight, silicon in about the range of from 0.30 to 1.50 percent by weight, sulphur in about the range of from 0.0 to 0.1 percent by weight with the remainder substantially all iron, trace elements and impurities. The substantially martensite-free micro-structure is characterized by the presence of one or more of the group consisting of lower bainite, upper bainite, pearlite or ferrite and mixtures thereof, thus providing a more ductile abrasive particle of improved wear resistance.
