The object of casehardening is to produce articles of steel having a tough or ductile interior and a hard sur­face. Quenching produces a surface somewhat harder than the interior, but in order to obtain a high surface hard­ness, the percentage of alloying elements in the steel must be raised to such an extent that the core or central por­tion becomes hard and brittle also.
