Abstract

A previously described salt bath apparatus for high temperature heat treatment of steel is made more effective through replacement of Ca pellets by a dense graphite rod as the deoxidation agent and the compartmentalization of the salt bath to avoid contact between the steel specimens and the graphite. Carbon content changes during subsequent, lower temperature heat treatment in a lead bath are inhibited by enclosing each specimen in a pouch made from the same material and by solidified salt trapped within the pouch.
