Abstract
The surface hardening diffusion process for an austenitic material such as 300-series stainless steel uses a pack carburization process at a temperature range from about 1500.degree. F. to about 2500.degree. F. for a period of time ranging from about one (1) to about eight (8) hours. Chromium carbides are formed on the surface of the austenitic material for increasing its wear resistance.
