Q What is the difference between bi-metal, ceramic, chrome-plated, and high-frequency quenching cylinder liners?

A
| Type | Inner Material | Hardness | Service Life | Best For |
| Bi-Metal | High-chromium cast iron | HRC 62 | 800h+ | General high-pressure, abrasive drilling |
| Ceramic | Al₂O₃ or Zirconia | HRC 80+ | 1500h+ | Extreme abrasion, high-sand formations |
| Chrome-Plated | Hard chrome coating | HRC 55 | 300-400h | Moderate conditions, budget operations |
| High-Frequency Quenching | Quenched alloy iron | HRC 50 | 200-300h | Light-duty, low-cost applications |
