Shot Peening Ductile Iron
Shot peening is a production process too often confused and used synonymously with shot blasting. They are not the same nor are the benefits of each interchangeable.
In the foundry industry, shot blasting is used to clean castings and remove scale; shot peening is a much more controlled process used primarily to:
* combat fatigue problems;
* prevent stress corrosion cracking;
* assist in form or shape correction;
* provide a uniform texture.
