Computer Controlled atmospheric heat treatment is another beneficial aspect of Great Lakes Metal Treating.

Two Surface Combustion AllCASE Batch Integral Quench Furnaces, each with a capacity up to 4,000 lbs, perform treatment processes such as normalizing, stress relief, oil quenching, annealing, carbon restoration and gas carburizing.

The furnaces operate under an endothermic atmosphere which yields treated parts with extremely clean surface finishes to ease the subsequent final machining processes. Presently processes have been developed for treating numerous alloys in various shapes and sizes. 'Stop-off' paint can be applied to protect from unwanted treatment on particular surfaces.
