Product Description Product DescriptionHigh Quality forged balls for grinding From D20 to D150, from carbon steel to Cr steel and Mn Steel or B2 B3 B6,Packed by single drum/pallet or double drum/pallet, just simply tell us your need and we'll settle down! Producing process:1. After checking and testing the round alloy steel bar material,the production can be started according to the sizeof the steel ball2.The steel forging is heated to a certain temperature by intermediating with frequency furnace to ensure theeffective generation of variables in the forging; 3.The red-hot steel forging is sent into the air hammer and processed by skilled operators. 4.After forging the red hot steel ball immediately into specially designed heat treatment equipmentfor quenching and tempering heat treatment, the high and uniform hardness value of the steel ball can be ensured.
