Beschreibung
Zusammenfassung:	The invention relates to a cold work steel alloy for the powder metallurgical manufacture of parts, in particular tools with improved functional quality. In order to simultaneously set the important property features of bend fracture strength, impact bending work and wear resistance at a high level, it is essentially provided according to the invention to use an alloy containing in percent by weight and accompanying elements up to 2.6 and production-related impurities with the balance being iron (Fe) as a material for the powder metallurgical manufacture of parts having an oxygen (O) content of less than 100 ppm and a content and configuration of nonmetallic inclusions corresponding to a K0 value of a maximum of 3 according to testing according to DIN 50 602.
