ABSTRACT:
The invention provides means for processing novel heat treated parts, eliminating danger of contamination of the parts from contaminating ambient or other air and gases. The invention further assures uniform, maximum efficiency in achieving the special hardening and other characteristics of the parts, without contamination thereof, thus obviating the necessity for any supplementary procedures for elimination of warping and other defects which might otherwise occur. The invention automatically and economically achieves the above recited and other objectives, thus assuring uniformity of desired characteristics, qualities and properties in heat treatment procedures, the operations being performed at or above atmospheric pressure thus preventing vaporization of certain alloying elements in the work and container metals.
