The PEC’s Shot Peening facility enhances metal fatigue properties through surface treatment of a range of metallic parts. The purpose of Shot Peening is to provide cold working by inducing compression stresses on a metallic surface. The residual stresses, deriving from machining, welding or any other operation can, as a result, be modified. Shot Peening is specifically used for Titanium-based Alloys, High Alloy or Tool Steels and Corrosion Resistance Steels (CRES), to reduce the shrinkage stresses, to avoid formation of shrinkage cracks and also the effect of fatigue or cyclic load/stresses.
Shot Peening is an excellent method for improving resistance to fatigue, stress corrosion cracking, and galling.
- The key features and capabilities of this powerful machine are:
- Six automated nozzles and one manual nozzle. Parameters are controlled by PLC programming
- The maximum capacity of shot flow rate is 20 lb/min
- The maximum achievable intensity is 0.009A noted by Almen strips.
The PEC’s world-class Shot Peening facility is approved by BOEING in accordance with BAC 5730N and BSS 7630.
