High chrome cast ball is a professional wear-resistant grinding media widely used in ball mill systems for mining, cement, power plant and industrial raw material grinding. Manufactured by medium-frequency electric furnace melting, metal mold casting and precise quenching & tempering heat treatment, our high chrome cast balls feature stable metallographic structure, uniform hardness and excellent comprehensive mechanical performance.

We supply full series high chrome grinding media including Cr12, Cr15, Cr20 and Cr26 grades. The chromium content is over 10%, which forms dense and hard M7C3 chromium carbide phases inside the ball, providing far higher wear resistance than low chrome balls and forged steel balls.

Core Performance Advantages

1. Super High Hardness & Wear Resistance

Overall hardness reaches HRC 58-66 with consistent hardness from surface to core. The special alloy formula greatly reduces grinding loss, effectively lowering your consumption cost per ton of ore or cement clinker.

2. Ultra Low Broken Rate & Stable Operation

Strict heat treatment process ensures impact toughness ≥3.0J/cm². The actual broken rate is controlled below 0.3%, avoiding ball breaking, out-of-round and mill blockage problems. It stabilizes ball gradation and improves mill output continuously.

3. Excellent Corrosion Resistance

High chrome alloy structure resists oxidation and slurry corrosion, perfectly suitable for wet grinding conditions in mineral processing. It performs much better than ordinary forged steel balls in humid and alkaline grinding environments.

4. Long Service Life & Lower Comprehensive Cost

Compared with low chrome cast balls, our high chrome grinding media has 2-3 times longer service life. Although the unit price is slightly higher, it greatly reduces replacement frequency, downtime loss and overall grinding media consumption, bringing obvious cost advantages for long-term production.
