Abstract

The invention relates to a method for producing powder-metallurgical steel. Said method consists of the following steps: a steel powder, preferably having a predetermined structure, is produced; the steel powder is mixed with a binding agent to form a plastically deformable raw material; the raw material is initially shaped to form a blank having a predefined spatial form; and the blank is sintered.
