Outstanding performance in peening of metallic surfaces
Shot peening with Zirshot HDC allows achieving:
- Higher compressive stress up to subsurface layers
- Smooth and homogeneous finish that minimizes crack initiation
- No particle embedment
- Durable and stable media even at high peening intensities
Thanks to its exceptional properties, Zirshot HDC opens new technical capabilities to enhance fatigue strength of metallic parts processed by ceramic shot peening treatments.


Guaranteed quality and versatility
Because quality of the peening media is a critical parameter that directly impacts the service life of treated components, ZirPro manufactures shot peening media using tightly controlled procedures and specifications, enabling Zirshot HDC to conform to the most stringent aerospace and automotive ceramic shot peening standards.
The versatility of Zirshot product line makes it applicable to all types of shot peening processes ranging from wet pressure to pneumatic pressure or suction to wheel turbine machines including the use of robotized equipment. Technical support is available at ZirPro application labs to assist customers in testing and setting up peening processes to maximize the performance of Zirshot HDC ceramic beads.
