Shot peening
What is shot peening?
Description shot peening
Shot Peening is as simple as the process of shot blasting, but with a perfectly controlled process, creating a high value activity, the most technical one among metallic abrasives applications. Winoa’s expertise and know-how are key factors for your success in reaching this application’s high level of performances.
Shot peening process is used in multiple industries to extend the service life of a component. The process induces a compressive stress layer to increase resistance to fatigue (propagation of cracks, stress corrosion, etc).
To name a few, peening are used on automotive parts (gear, cams, clutch, coil and suspension spings) to aerospace (landing gears to turbine blades), energy sector (rock drills and windmill gears) to Railcars (wheels and coupling peening) and many others.

High Durability Cut Wire
Our high-durability conditioned Cut-Wire, manufactured by our partner Toyo Seiko in Japan (the world leading company for shot-peening media), is a specially heat-treated Cut-Wire for an extended shot life-time.
This extended life not only reduces shot consumption, but for critical peening applications, it ensures a more constant operating mix and peening shot size, reduces variables related to shot addition and control, resulting in a safer peening process.

UFS Ultra Fine Shot
When some applications requires very small beads due to sharp radius and for precise shot peening, our high hardness, highly spherical shape high carbon micro shot will meet your needs.
With average sizes from 50 µm to 150 µm, and with a hardness above 770 Hv (63 RHc), our UFS shot is your solution to treat these complex shapes. They are commonly used in peening gears for electric cars, springs or molds, but also for dual peening to increase compressive residual stress on the outer layer of the surface.

Moreover, in order to optimize the complex shot peening process, it is not enough to have a good shot, you need the tools and accessories to control the peening.
To do this, trust our peening accessories. Whether it’s W Abrasives Almen strips to the Almen strip holder, or the Almen Gauge to an automated Coverage Checker made by our partner Toyo Seiko, trust our experts to advise you on our tools.
Frequently Asked Questions (FAQ) about peening
Key inquiries in peening
Shot peening extends the service life of components across various industries, inducing a compressive stress layer to enhance resistance to fatigue, stress corrosion, and other detrimental effects.
Shot peening offers benefits such as increased component life, resistance to fatigue, and improved material properties, crucial in various industries.
Shot peening may face limitations if a component’s surface is too hard or if the surface temperature surpasses the metal’s normalizing temperature, leading to the loss of crucial residual compressive stresses. Moreover, the process demands an open surface for direct shot impingement, posing challenges when dealing with blind or inaccessible areas.
The ISO-26910 standard provides international guidelines for shot peening processes, ensuring industry-wide quality and consistency. For the shot media used, standards such as SAE AMS2431, SAE J444, and ISO 11124 provide detailed specifications on the media’s physical properties like shape, size, and hardness. These standards are crucial for achieving effective shot peening results, enhancing the durability and fatigue life of treated components by ensuring the media used meets rigorous quality criteria. Compliance with these standards guarantees the integrity and effectiveness of the shot peening process.
