There are three types of steel balls: forged steel balls, cast steel balls, and hot-rolled steel balls.
Forged steel ball:
Forged steel ball is made of round steel after being cut by air hammer. The wear resistance of the forged steel ball has a great relationship with the material of the round steel used and the impurities or the quality of the round steel.
45# steel, and more than 50mn and 60mn or 65mn. At present, the wear resistance of 75mncr is comparable to that of high chromium balls.
the crushing rate is less than 1%, the wear resistance is good, the price is cheap, and the cost performance is high.
