Stack Metallurgical Endothermic Heat Treating Furnace 122

Endothermic Department

With the addition of new Surface Allcase IQ and McLaughlin Temper furnaces our Endothermic Department now has a total of twenty-four furnaces for hardening, carburizing, tempering, normalizing, annealing and stress relieving.  The size of our furnaces range from small tooling furnaces, 22” deep x 16” wide x 32” high, designed for a few hundred pounds to large production furnaces 72” deep by 36” wide x 36” high.  This wide selection of capacities has helped Stack Metallurgical Services become the Northwest’s premier heat treating company.
