摘要：
Highly dense shaped parts are produced with a powder metallurgic process. The parts are formed of an alloy that, besides of at least 20 weight % chromium, consists of iron and one or several additional alloy portions that in sum do not amount to more than 10 weight %. The part is produced by pressing and sintering to near final shape a ready-to-press powder where the additional alloy portions are introduced in form of a master-alloy powder. The master-alloy may contain the following variations: the additional alloy portions and the iron portions; or the additional alloy portions, the iron parts, and the chromium portions; or additional alloy portions and the chromium portions.
