Plasma Nitriding Surface Treatment Flanges
- Plasma Nitriding Surface: A special heat treatment method that hardens the flange surface for superior wear resistance.
- Hardness and Depth: Plasma nitriding depth of up to 0.07mm with hardness reaching 1250HV1 or more.
- High Dimensional Accuracy: Tolerance control within 0.01mm to ensure precision even after heat treatment.
- Durability: Significantly enhances the longevity of flanges in high-wear environments.
- Customization: Manufactured according to customer-specific drawings and requirements.
