Abstract
A method of making sintered components made from an iron-based powder composition and the sintered component per se. The method is especially suited for producing components which will be subjected to wear at elevated temperatures, consequently the components consists of a heat resistant stainless steel with hard phases including chromium carbo-nitrides. Examples of such components are parts in turbochargers for internal combustion engines.
