Process Details
The Stress Relieving Temperature Is Normally Between 550 And 650°C For Steel Parts. Soaking Time Is About One To Two Hours. After The Soaking Time The Components Should Be Cooled Down Slowly In The Furnace Or In Air. A Slow Cooling Speed Is Important To Avoid Tensions Caused By Temperature Differences In The Material, This Is Especially Important When Stress Relieving Larger Components.
If Necessary, Stress Relieving Can Be Performed In A Furnace With Protective Gas, To Protect Surfaces From Oxidation. In Extreme Conditions Vacuum Furnaces Can Be Used.
