Heat treatment and finish
- Austempering is applied to increase the mechanical property of our products. Our modern heat treatment equipment and skillful technicians guarantee each retaining ring within the mechanical properties required.
- The standard finish of carbon steel retaining rings is phosphate.  
- Dacromet is available on request.
- Zinc plating is available, but is not recommended because of the risk of hydrogen brittleness.
- Stainless steel is polished into original color after heat treatment.
