Introducing the excellent performance of Pionite. It has wear resistance dozens of times greater than hard chrome plating and equal to or better than nitriding treatment, significantly improving the durability of products. The flexible hardened layer of austenitic structure remarkably enhances fatigue strength, extending the lifespan of thin-walled and small-diameter components and increasing design flexibility. Additionally, Pionite demonstrates a stable torque coefficient, effectively preventing seizure in fastening components such as bolts. 【Features】 ■ Wear Resistance: Significantly improves product durability ■ Fatigue Strength: Extends the lifespan of thin-walled and small-diameter components and increases design flexibility ■ Anti-Seizure Properties: Effectively prevents seizure in fastening components such as bolts *For more details, please refer to the related link page or feel free to contact us.
