Autofrettage Benefits Autofrettage provides the following benefits: Autofrettage increases the working pressure components can operate at without failing. In the case of pipework, working pressure can ...

Autofrettage: A mechanical process that induces plastic deformation in the inner layers of a thick-walled cylinder to generate beneficial compressive residual stresses and enhance fatigue strength.

Specially designed robotic machines perform the autofrettage process, a sophisticated method of strengthening the injection tubing for long-term reliability, according to TI Automotive.
