Shot-peening of stainless steel compression springs improves their fatigue performance by creating beneficial compressive residual stresses.
Shot-peening also work hardens the spring surface, changes the surface topography and some say, takes away defects and de-carburization, and all these factors contribute to the beneficial effect upon spring fatigue performance.
At Shannon Coiled Springs we offer shot-peening as an optional extra finish, we would be delighted to discuss your requirements on 061 – 311666.
