ABSTRACT:
A process is provided for heating steel powder compacts in a controlled atmosphere consisting of a primary gas containing at least 80% by volume of an inert gas, and a secondary gas comprising 0.1 to 5% by volume, based on the volume of said primary gas, of a paraffinic hydrocarbon. The process makes it possible to reduce the residual oxygen concentration in the steel powder compacts, while maintaining accurate control of the carbon content.
