Reasons For Stress Relieving Steel Components

While steel parts are ideal for many designs, it does present challenges. One issue that needs to be addressed in the manufacturing process is the stress relieving steel after it has been worked.

Processes such as hot rolling, grinding, welding, quenching, cold working, and any type of cutting can create stress at a granular level of the steel, as well as with other types of metals and alloys. Suring the process of stress relieving steel, the interior structure of the metal is realigned, which causes the stress relief. This eliminates the risk of failure, and increases life cycles.

It is important to realize that some processes, particularly with large areas of welding, it may not be possible to completely relieve stress. However, with right process, it can be relieved to the point where it will not have a significant impact on the final product.

The Thermal Advantage

While it is possible to relieve the stress in metals through a variety of processes, thermal treatments are considered the most effective in most cases. During thermal stress relief, the material put through a precisely controlled temperature increase, and is held at a specific temperature for an exact amount of time. The temperature and the time will be set but the type of steel, and other factors.

After the period of uniform heating and holding, the part is then air cooled slowly, in still air. This is essential, as using moving air, cools the metal too fast, preventing the desired stress relief.

Through stress relieving steel, it is possible to not only make the metal stronger, and more resistant to fatigue and failure, but to also remove distortions in an area of welding that may impact the aesthetics of the part.
