Abstract

A machinability improving and/or wear-resistance improving supplementary powder for an iron- or steel-based powder for use in powder-metallurgical production of blanks consists of MnS and Te or a Te-compound and/or Se or an Se-compound. For the supplementary powder, an iron or steel powder containing the same and a blank which is powder-metallurgically produced from the iron or steel powder, the weight ratio between MnS and Te should be in the range of 10-2000, the weight ratio between MnS and Se should be in the range of 10-1000, and, when both Te and Se are used, the limiting values of this range should be doubled.
