• Impact machining generally will increase the tensile strength from 30% to 120% and yield strength from 60 to 150% depending on the amount of movement and deformation.

 

  • Material that has been machined through impact develops continuous contoured grain flow lines. These flow lines help improve the physical properties.

 

  • With smooth finishes also produced by impact, and the absence of stress inducing tool marks, the favorable grain flow pattern provides an improved resistance to shock and fatigue failure.
