Normalizing
Normalizing is a process aimed at refining the grain and relieving stress in the blades before hardening when necessary. Condursal Z1100 can be used to reduce surface decarburization and scaling. Recommended time and temperature for varying thicknesses. Once the knife has cooled and becomes black and magnetic, it can be reinserted into the oven.
