Maximum load - minimum space - maximum flexibility

shot peening

It has been shown that shot peening can be very beneficial to springs subjected to dynamic loads. It can considerably improve the working life far in excess of the values shown in figures 18, 19 and 20.

Shot peening produces compressive stress at the surface which partially counteracts internal tensile stress resulting from setting. Therefore shot-peened springs will generally set more than usual. For this reason, surface bonding by means of shot peening is not recommended for springs carrying static loads.
