What type of treatment would be used in making a scalple blade?

Scalpel blades are typically made from high-carbon stainless steel, which undergoes heat treatment to enhance their hardness and durability. This process involves heating the steel to a specific temperature and then rapidly cooling it, known as quenching, followed by tempering to relieve internal stresses. The treatment results in a sharp, strong blade suitable for precise surgical procedures. Additionally, some blades may be coated to improve corrosion resistance and reduce friction.
