Hardenability is the depth to which a steel is hardened after putting it through a heat treatment process. It should not be confused with hardness, which is a measure of a sample's resistance to indentation or scratching.[1] It is an important property for welding, since it is inversely proportional to weldability, that is, the ease of welding a material.
