Shot peening is a method to improve the operating life of your spring by creating beneficial compressive residual stress. We are able to shot peen a spring with wire diameters ranging from 0.010 inches up to 3.5 inches. Shot peening can increase the operating life by 5 to 10 times more when compared to un-peened spring.

How it works:

shot peeningShot peening is a cold working process in which small spheres called shot to bombard the surface of your spring at high velocity under controlled conditions. This creates compressive residual stress which delays the initiation of fatigue cracking and strengthens your spring thus improving the fatigue life of your spring.

Benefits of Shot Peening:

  • Enhance fatigue strength
  • Prevents cracking due to wear
  • Prevents corrosion
  • Prevents hydrogen embrittlement
