      It has been estimated that 50% of all the components that should be stress relieved are not.<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
      \n\t\t\t\t

      Often the reason cited for skipping stress relieving is based upon the desire to avoid unwanted side effects associated with heat treatment.<\/h5>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      \n\t\t\t\t
      \n\t\t\t\t\t

      \u2022 The risk is in hoping that no problems will arise normally cracking, distortion, or a reduction in the component life cycle.
      \u2022<\/strong> A bigger, often forgotten risk, is any of the above will often generate dissatisfied customers.
      \u2022<\/strong> As VSR does not cause any of the mentioned unwanted side effects and the process is virtually limitless in size and weight capabilities not stress relieving is unnecessary.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
