Vacuum Stress Relieving Furnace Manufacturer

What is the Vacuum Stress Relieving Furnace?

The specialised furnaces manufactured by Therelek for the purpose of stress-relieving of articles made of various metals, non-ferrous materials and ferrous alloys. These furnaces are known to produce extremely fine results. They are capable of stress relieving items of various dimensions. 


Stress relieving process is supposed to remove or reduce certain residual stresses induced in tools by heavy machining or while forming. Hence the probability of the tool getting distorted or cracked up during its hardening, gets reduced; when carried out by a Therelek vacuum stress relieving furnace. The induced stress is relieved by this furnace; however some considerations may be required when it comes to long slender items or plates having heavy cold work.

Vacuum stress relieving is also known as sub-critical annealing, as it is the range of temperature involved herein is near around the point at which austenite starts forming. Hence it is all the more important to be cautious while carrying out the process. Therelek hence takes extra care while manufacturing such furnaces.
