Abstract

The invention describes a method of producing a sinter-hardened component from a metallic powder containing chromium which is pre-alloyed in particular, comprising the steps of compacting the powder to form a green compact and then sintering the green compact in a reducing sintering atmosphere at a sintering temperature in excess of 1100° C. A gas containing carbon is added to the sintering atmosphere.
