• No Distortion in product
• No Warping of product
• Better consistency in casting dimensions 

Description of process:

          Stress Relieving is a process used for reducing or eliminating stresses in iron castings by reheating and cooling them at a controlled rate.  High stress in castings can cause distortion or warping especially during machining.  The most common reasons for high stress in castings are non-uniform section thickness or differences in surface cooling rates and internal cooling rates for the same section.  

         Uniform or thick section castings normally have low residual stress, while thin or uneven sectioned castings retain higher residual stress.  By elevating temperature between 900 and 1200 F and holding for a predetermined time, then allowing the casting to cool at a controlled rate, most if not all stress can be eliminated from the product.  Yield strength will not be affected by this process.

Capability
