Retort type furnaces can be used in a variety of ways. Be it for tempering and annealing of tools previously processed in vacuum hardening furnaces, as well as for a number of other heat treatment processes. The latter include in particular the processes of gas nitriding, nitrocarburizing in conjunction with corrosion-protective post-treatment (oxidizing). Our retort furnaces are available in a wide variety of designs. You can choose between electric heated or gas heated versions.
