Detailed Product Description Bearing Steel Ball

ONE  Material: GCr15 high chrome

TWO  Production Process:
1) Heating: heat the raw materials
2) Forging and Stamping: In this step, machines cut wire into short lengths and form it into spherical shapes.
3) Heat Treatment: heat treatment imparts the desired hardness.

three  Main Features: 
high hardness, ground resistance, without loss of circle, low broken rate, high efficiency in grinding and etc.

four Application Domain: 
cement works, mine, mineral processing, thermal power, chemical industry and etc.
