Service Heat Treating, a commercial heat-treating company located in Milwaukee, Wis., has developed an alternative heat-treatment process known as WearAll that has shown to provide better wear resistance than carbonitriding for a number of critical-service components.

The terms sound alike and often cause confusion, but nitrocarburizing and carbonitriding are distinct heat-treating processes.

Carbonitriding studies with a high amount of nitrogen are characterized by adding ammonia to the process gas at a higher rate than the usual 3-5%. This work focuses on the impact of nitrogen on the lifetime of carburized parts (e.g. gears, sprockets, bearings, crankshafts) exposed to Hertzian pressure or fatigue.

You have heard the terms carbonitriding and nitrocarburizing and know they are two different case-hardening processes, but what are the real differences between them?
