Shot Peening
Shot peening is a controlled mechanical surface treatment that introduces compressive residual stresses into metal surfaces through repeated impacts from spherical media. It is widely used for springs, gears, shafts, aerospace components, and fatigue-sensitive parts requiring improved resistance to cyclic loading.

Manufacturing overview
Shot peening uses controlled impacts from small spherical particles to plastically deform the surface of a metal component.
This process creates compressive residual stresses that can improve fatigue resistance and reduce susceptibility to certain surface-initiated cracks under appropriate conditions.
Typical applications include gears, springs, turbine components, shafts, connecting rods, and high-stress mechanical parts.
Suitable materials include alloy steel, stainless steel, titanium alloys, aluminum alloys, and other compatible metals.
Important process parameters include shot size, media hardness, impact velocity, coverage, intensity, and treatment area.
Shot peening differs from conventional abrasive blasting because its primary purpose is controlled residual stress modification rather than surface cleaning.
Process intensity is commonly evaluated using Almen strips, while coverage and media condition require separate controls.
Buyers should specify material grade, component geometry, treatment zones, required intensity, coverage, quantity, and applicable process standard.
Relevant specifications may include SAE AMS2430 and application-specific aerospace or industrial requirements.
Quality verification may include Almen intensity testing, coverage assessment, media inspection, and documented process control.
Metraxio supports shot peening RFQs for fatigue-sensitive components requiring controlled surface treatment and traceable quality documentation.
