Abstract:  
Introduction Todays production of dynamically stressed components in many industrial branches requires Shot Peening applications with a high level of optimized processes and materials. The media used in that processes is becoming more important to achieve best results at the parts surface and to run the application in the most economical way. This recognition was the reason for a two years research at R+K Draht GmbH to develop a Conditioned Cut Wire Shot (Special Quality") that corresponds to the a.m. needs much better than conventional well known Conditioned Cut Wire is doing today. The extensive research period was finished in 1999 and was continued by a period of large scale tests in industries with various applications. Special Quality showed its drastic increased lifetime and provides industries a shot peening media that allowes to run also applications where hardnesses with 700 HV (60 HRC) and above are needed in an economical way for the first time. The following presentation shows the results that could be achieved in industrial applications during the last years.
