Abstract: Gas nitriding is well established as a suitable process for realising low distortion in precision parts under optimal conditions. However, efforts for optimising the distortions by trial and error, which are not avoidable, have been repeated over many years. A software tool based on the finite element method is developed by use of the latest models of nitriding for resolving the problems, which was applied to the nitrided austenitic stainless steels specimens. In this study, distortions in nitrided steel cylinders, which were measured systematically in 1930s, were investigated using the tool for understanding their tendencies derived from different conditions. The fruits will be used for enhancing the tool by additional verifications, and applying finally to distortion problems in practical parts.
