Stress Relieving

Stress Relieving

In this process, steel is heated at around 595 ℃(1105℉) approximately by ensuring that the entire part is heated uniformly. Soaking time is about one to four hours depending on cross-section. Then cooled slowly back to room temperature. If necessary, stress-relieving can be performed in a furnace with protective gas, to protect surfaces from oxidation. For critical components, vacuum furnaces can be used.

Stress relieving is normally done after rough machining, but before final finishing such as polishing or grinding.

Why Stress Relieving?

Internal stresses are developed during different operations like a solidification of castings, welding, machining, grinding, shot peening, surface hammering, cold working, case hardening, electroplated coatings, precipitation, and phase transformation. This kind of stress also increases the tendency of steels towards warpage and dimensional instability.

Stress relieving is used to minimize residual stresses in the part or assembly to reduce the risk of dimensional changes during further manufacturing and heat treatment or final use of the component.
All materials can be stress relieved.
The process is used to reduce internal stresses.
Process takes 2 days for the treatment.

We charge based on the weight (kg) of material, however, pricing depends on the maximum number of pieces that can be treated at once. For details, please contact us.
