Abstract

PURPOSE:To manufacture the title high Cr steel by subjecting a powder Cr source to ultra low nitriding treatment with a flux consisting of alkali (earth) metals and their halides and mixing the treated source with oxides after which the mixt. is melted along with electrolytic iron, etc. in a vacuum furnace while preventing absorption of nitrogen.
