Description

technical field [0001] The invention relates to the technical field of wear-resistant steel balls, in particular to a corrosion-resistant, impact-resistant and wear-resistant steel ball and a preparation method thereof. Background technique [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-mentioned industries for wear-resistant steel balls, so it is necessary to provide a new corrosion-resistant, impact-resistant and wear-resistant steel ball. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a corrosion-resistant, impact-resista...
