Abstract

1. Inert salt bath for heating steels to austenitizing temperature, consisting of a mixture of essentially alkaline and alkaline earth chlorides and a regenerator, characterized in that from 0,01 to 2 % by weight of a polymeric carbon and nitrogen-containing organic compound are added to the salt mixture as regenerator.
