ATMOSPHERE HEAT TREATING Here's where the tough get tougher. This treatment is used to increase the hardness of the outer surface. The combination of a hard, abrasion resistant surface and a high strength core is greatly valued in modern engineering because it can withstand very high stress and fatigue. Our vacuum heat treating service is a precisely controlled, environmentally friendly process that results in minimal distortion with a bright, scale-free finish which can eliminate polishing and grinding. Ion nitriding, or plasma nitriding, is currently one of the most technologically advanced methods for case hardening of steel components. Black Oxide is a chemical conversion coating for ferrous materials. Serving the Southeast with Heat Treating and metallurgical service since 1985. "Our furnaces make your products harder.
