Abstract
Method for the production of a wear resistant part of a soil working tool comprising forming a mixture of 67-90% by volume of iron particles consisting of at least 97% Fe and 10-33% by volume of hard particles having a desired particle size distribution, and subsequently pressing the mixture at a pressure of at least 3500 kp/cm.sup.2 to form a compact, sintering the compact at a temperature of 900.degree.-1200.degree. C., and optionally sinter forging the sintered compact. The sintered part consists of an iron matrix in which hard particles with a predetermined particle size distribution are embedded.
