NOTE: We can adjust the material to meet different customers’ different requirement of Chemical composition, property and price and so on.
B. Production technology: Huamin mainly have three kind of production technology for forged steel balls.
One technology is using air hammer, the second is rolling-forged automatic production line designed by our ourselves, this production line is controlled by automatic equipment, so the hardness is high and toughness is good. The third one is our Rotary-cut automatic production line, this production line gets five national patent. Currently, we mainly use production line to produce forged steel balls,so the product quality is quite steady and good.
