Abstract
This invention concerns a production process of ferrite stainless steel covered with oxide whisker suitable for metal catalyst supports in automobile's exhaust gas converters, which comprises plating a ferrite stainless steel with aluminum, diffusing the aluminum into the stainless steel by heating in vacuum or in a non-oxidizing gas so that the surface of the ferrite stainless steel turns into an aluminum-enriched ferrite phase, and allowing oxide whisker to grow there by heating in the air.
