Frequently Asked Questions
High chrome balls (typically ≥10% Cr) offer significantly higher hardness and wear resistance, making them suitable for abrasive materials, whereas low chrome balls are often used in applications requiring different toughness profiles.
They are essential in the cement industry for clinker grinding, the mineral industry for ore processing, the steel industry for sintered pellets, and the power industry for pulverized coal grinding.
We perform technical analysis and test work on your specific materials to recommend the ideal grade from our ZQCr series (ranging from 2% to 28% chrome) to balance hardness and impact resistance.
Our products typically range from 58 to 68 HRC, ensuring they remain effective in high-intensity crushing and grinding environments.
Yes, we offer a wide range of customized sizes from 4.6mm up to 150mm to fit various mill specifications and application requirements.
Oil quenching allows for a controlled cooling process that optimizes the microstructure (Martensite + Carbide), resulting in a lower broken rate and higher toughness.
