Vibratory vs. Thermal Stress Relieving

Comparing Two Approaches to Residual-Stress Management
Formula 62® VSR provides a rapid, non-thermal alternative to conventional furnace stress relieving for suitable components and applications. It is not a universal replacement where thermal PWHT is mandatory.

VSR vs. Traditional Thermal Stress Relieving

Traditional furnace stress relieving can involve heating and cooling cycles, extended processing time and transportation requirements. Formula 62® VSR offers a non-thermal At-Site alternative for suitable applications.

Parameter	Formula 62® VSR	Thermal Stress Relieving
Processing Time	Approx. 30–60 min per treatment zone	Extended heating, soaking and controlled cooling cycle
Component Size & weight	Large/heavy components can be treated At-Site	Limited by furnace capacity and transport logistics
Surface condition	No furnace scale or heat-induced oxidation	May require post-treatment descaling/cleaning
Transportation	Can reduce or avoid transport to heat-treatment facility	Often requires transport/handling for external furnace treatment
Thermal distortion	Avoids furnace heating/cooling, helping minimize heat-induced distortion	Thermal cycle may introduce dimensional change depending on component
Material properties	Avoids elevated treatment temperature; preserves existing properties subject to application	Thermal cycle intentionally exposes material to elevated temperature
Energy requirement	Significantly lower energy requirement than furnace heating for suitable applications	High energy demand for heating furnace and component
At-Site capability	Mobile process at point of manufacture/repair	Normally furnace-based
Production flexibility	Can be integrated into manufacturing/repair sequence	Dependent on furnace scheduling and handling

Why Transport the Component to the Furnace When the VSR Process Can Be Brought to the Component?

Formula 62® VSR combines non-thermal residual-stress management with At-Site mobility, rapid treatment cycles and documented process monitoring.
