A Series

This series consists of representative models of small-scale heat treatment furnaces used for nonoxidation quenching of small-lot parts. Models best suited for machinery structural steels (carbonsteels, alloy steels) and tool steels (cold work die steels, hot work die steels, plastic mold steels)
are available. Since heat treatment is performed in a non-oxidation atmosphere, oxidation anddecarburization can be restricted.
