Is nitriding cookware safe to use?

Nitriding is a heat treatment process that diffuses nitrogen into the metal surface to improve its hardness, wear resistance and fatigue strength. The nitriding treatment process can be applied to various types of steel and cast iron to improve their surface properties. Nitriding is commonly used to make metal industrial parts on equipment such as engines, valves, and industrial pumps. It is also used in gunsmithing to strengthen steel components of weapons.

Overall, nitriding is a valuable case hardening process that can significantly improve the performance and durability of cast iron components in a variety of industrial applications.
