Cost
What it costs
Bombards the surface to induce compressive stress and raise fatigue life on cyclically-loaded parts (springs, gears, shafts).
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for your part at your volume, in your currency, are in the dossier.

What does Shot Peening cost per part?
It depends on size, tolerance and volume. As a rough ballpark it starts around $5.4 to 9.3 per part at low volume and falls with quantity. The dossier gives should-cost at your exact volume and currency. Model estimates, not quotes.
What tolerance can Shot Peening hold?
It depends on the feature and the finishing operations used.
What materials suit Shot Peening?
Common choices are (fatigue-loaded steels/alloys) (n/a).
