karkaistukset
Karkaistukset is a Finnish term that refers to the process of hardening metals, typically steel, through controlled heating and cooling. This metallurgical treatment is designed to increase the material's strength, hardness, and wear resistance. The fundamental principle behind karkaistukset involves altering the metal's microstructure.
The process begins with heating the metal to a specific temperature, known as the austenitizing temperature.
Following the quenching, the metal is often subjected to a tempering process. Tempering involves reheating the
