Problems solved by technology

[0002] With the rapid development of domestic and foreign mining, construction, metallurgy, chemical industry, power plant, cement and other industries, the demand for wear-resistant steel balls is increasing, and the working environment of wear-resistant steel balls is getting worse and worse. The impact resistance, wear resistance and corrosion resistance of the ball can no longer meet the requirements of the above industries for wear-resistant steel balls, so it is necessary to provide a new corrosion-resistant, impact-resistant and wear-resistant steel ball
