Stress relief annealing is a crucial heat treatment technique used to reduce internal stresses in metals. Regardless of the metalworking industry you’re involved in, the right type of heat treatment can make a significant difference. When is stress relief annealing applicable? You’ll find out in this text.
Stress relief annealing as heat treatment
The heat treatment process of stress relief annealing can be invaluable in various situations. Ultimately, it aims to reduce internal stresses that arise after welding, forming, machining, or casting. These internal stresses can develop due to the following:
- Welding: Thermal stresses often occur during welding processes.
- Mechanical Processing: Milling, turning, or stamping of metals can induce stresses that affect the structural integrity and dimensional stability.
- Metal Casting: Casting processes often introduce internal stresses due to uneven cooling.
- Extending Lifespan: By reducing internal stresses in metals, stress relief annealing helps prevent premature failure of components, leading to a longer lifespan for your products.
The process of stress relief annealing
The process of stress relief is carried out by heating the material in one of our furnaces. The temperature is kept just below the lower critical temperature for a certain time. Then it is slowly cooled. This process ensures that the strength of the material returns before it is formed. Thanks to this stress relief, the material has an increased (mechanical) strength and removes its irregularities.
