Endothermic Department
The Endothermic Department has a total of twenty two furnaces for hardening, carburizing, tempering, normalizing, annealing and stress relieving. The size of our furnaces range from small tooling furnaces, 22 x 16 x 32, designed for a few hundred pounds to large production furnaces 96 x 36 x 48. This wide selection of capacities has helped Stack Metallurgical Services become the Northwest's premier heat treating company.
