Technical Advantages of High Hardness Steel Balls
The core competitive advantage of Feige Steel Balls lies in our specialized production of high hardness wear-resistant steel balls. Through advanced heat treatment processes and precision grinding technology, our products achieve surface hardness of 60-67 HRC while maintaining excellent toughness. This unique combination enables our steel balls to withstand extreme working conditions including:
- High-speed rotation in bearing applications (up to 50,000 RPM)
- Heavy load conditions exceeding 500kg per ball
- Corrosive environments requiring stainless steel grades
- High-temperature operations up to 300°C
- Abrasive working media in mining equipment
Our material selection system includes bearing steel (GCr15), stainless steel (304/316/440C), carbon steel, and special alloy steels. Each material undergoes strict chemical composition analysis and metallographic inspection before production. The precision grinding process ensures dimensional accuracy within ±0.001mm for G3-G10 grades, meeting the most demanding requirements of aerospace and medical equipment industries.
