Nitriding (QPQ) for Extreme Wear Resistance
Nitriding (QPQ) — Harder Surfaces, Longer Lifespans
When strength and reliability matter most, Manluk’s Quench-Polish-Quench (QPQ) nitriding process delivers. By diffusing nitrogen into the steel surface, we create a wear-resistant case layer that significantly boosts component hardness while maintaining core strength.
For industries where downtime is not an option, our nitriding treatments provide a proven way to extend component lifespan, reduce fatigue failures, and minimize friction. It’s precision-engineered protection, trusted by global leaders in oil, gas, and mining who require both performance and consistency.
