Abstract

The invention relates to a method for producing a metal alloy, in which in a vessel at overpressure a certain desired content of an alloying constituent, which is gaseous in its normal state, is fed to said metal alloy. The method is designed such that precise addition by alloying of an alloying constituent which is gaseous per se, to a steel alloy subjected to overpressure in a pressure vessel, is made possible.
