valssausta
Valssausta is a Finnish term referring to the process of tempering metal, specifically through controlled heating and cooling cycles. This thermal treatment is crucial for modifying the mechanical properties of metals, such as their hardness, ductility, and toughness. The primary goal of valssausta is to relieve internal stresses that may have developed during previous manufacturing processes like forging or welding, and to refine the grain structure of the material.
The valssausta process typically involves heating the metal to a specific temperature, holding it at that temperature
