Low Chromium Alloy Casting Balls
Low Chromium Alloy Casting Balls are made from cast steel with chromium content typically below 5%. This composition provides good toughness and moderate hardness, making them suitable for grinding softer ores such as coal, limestone, and cement clinker.
Product Showcase
The casting process ensures a dense and uniform microstructure, resulting in reliable wear resistance and impact strength. Low Chromium Alloy Casting Balls can withstand repeated grinding impact while maintaining stable performance in rotary mills.
