Usage Instructions

1. Installation Guidance: Avoid direct impact with hard tools like steel hammers during installation. Use dedicated tools or soft pads to prevent localized stress concentration and brittle fracture.

2. Counterface Materials: For optimal performance, the mating surface should be a hard material like tungsten carbide, hardened steel, or silicon nitride itself.

3. Environmental Note: While highly corrosion-resistant, prolonged exposure to hydrofluoric acid and hot, concentrated caustic solutions should be avoided.

4. Storage Conditions: Store in a dry, clean environment to prevent surface contamination.
