Shot Peening: Enhancing Metal Performance


in Precision Manufacturing

In the realm of metal fabrication, where durability, fatigue resistance, and structural integrity are non-negotiable, shot peening stands as a critical surface treatment process. As a specialized manufacturing facility, we integrate shot peening into our production lines to elevate the performance of metal components across industries. This article explores the science, parameters, and real-world applications of shot peening, shedding light on why it remains indispensable in modern metalworking.



What Is Shot Peening?

Shot peening is a cold working process that bombards a metal surface with small, spherical media (known as "shot") at high velocities. Unlike abrasive blasting, which focuses on cleaning or texturing surfaces, shot peening intentionally deforms the material’s outer layer to induce compressive residual stress. This stress counteracts tensile forces that cause fatigue cracks, significantly extending the component’s service life.
The process is governed by precise control over variables like shot size, velocity, and coverage—factors that directly impact the final material properties.



Key Shot Peening Parameters & Their Effects

To achieve consistent results, our facility adheres to strict parameters tailored to each component’s material and application. The table below outlines critical variables and their implications:
Parameter
Typical Range
Effect on Component Performance
Shot Material
Steel, Ceramic, Glass Beads
Steel shot for high strength; glass beads for delicate surfaces (e.g., aerospace parts).
Shot Size
0.2–2.0 mm
Larger shot increases compressive stress depth; smaller shot improves surface finish.
Intensity (Almen Arc)
0.005–0.030 A/B/C
Higher intensity = deeper residual stress (critical for high-load parts like gears, springs).
Coverage
100–200%
100% coverage ensures no unprocessed areas; 200% for critical components (e.g., turbine blades).
Peening Pressure
20–100 psi
Higher pressure increases shot velocity, enhancing stress penetration.
Exposure Time
10–60 seconds
Balanced to avoid over-peening (which can cause surface damage).


Why Shot Peening Matters: Core Benefits

  1. Fatigue Life Extension
By introducing compressive stress, shot peening delays the onset of crack propagation. For components like automotive springs or aircraft landing gear, this can extend service life by 300–500% compared to untreated parts.
  1. Improved Stress Corrosion Resistance
Compressive residual stress reduces the likelihood of corrosion-induced cracking, a critical advantage for marine or chemical processing equipment.
  1. Enhanced Mechanical Properties
The controlled plastic deformation of the surface layer increases hardness by 10–15% in most metals, improving wear resistance without compromising ductility.
  1. Cost Efficiency
Integrating shot peening into production reduces long-term maintenance and replacement costs, making it a cost-effective alternative to material upgrades.



Our Facility’s Shot Peening Capabilities

At our factory, we leverage state-of-the-art automated shot peening systems to ensure precision and repeatability. Our capabilities include:
  • Material Compatibility: Processing carbon steel, stainless steel, aluminum alloys, and titanium.
  • Customization: Tailoring parameters for small components (e.g., fasteners) to large industrial parts (e.g., engine blocks).
  • Quality Assurance: Post-peening inspections using Almen gages and surface profilometers to verify intensity and coverage.
  • Industry Compliance: Adherence to standards such as SAE J442, AMS 2430, and ISO 11124 for aerospace and automotive applications.



Applications Across Industries

Shot peening is integral to our production for clients in:
  • Aerospace: Strengthening turbine blades, jet engine components, and structural airframe parts.
  • Automotive: Enhancing durability in transmission gears, suspension springs, and drive shafts.
  • Energy: Protecting wind turbine gears and power generation equipment from cyclic loading.
  • Heavy Machinery: Extending the life of hydraulic cylinders and industrial bearings.



Conclusion

Shot peening is more than a surface treatment—it’s a precision engineering solution that transforms metal performance. At our facility, we combine technical expertise with advanced equipment to deliver shot peening services that meet the most demanding industry standards. Whether you require fatigue resistance, corrosion protection, or enhanced mechanical properties, our process ensures your components perform reliably under pressure.
