Study On The Performance Of High Chromium Cast Iron Balls With .

The effect of carbide content on the wear resistance of high chromium cast irons was evaluated by means of ball mill testing. Martensitic cast irons containing from 13 to 41% carbide volume fraction were evaluated. The tests compared also the performance of balls with martensitic, pearlitic or austenitic matrices. Test pieces.
