Beschreibung
Zusammenfassung:	PURPOSE:To produce a magnetic scale material which has, even at the time of use under a high temp., oxidizing, and corrosive severe environment, superior heat resistance, oxidation resistance, corrosion resistance, and high temp. strength and sufficient durability and is capable of having high detection precision, such as a rod with magnetic graduations for an EGR (Exhaust Gas Recirculation) device concerning automobile exhaust gas control. CONSTITUTION:Recessed parts 2 having prescribed shape and depth are formed on the surface of the parts, where graduations are to be formed, of a base material 1 of non-magnetic steel which has a composition consisting of, by weight,
