Abstract
A new technology has been introduced to the North American market as a potential replacement for conventional gas carburizing. This new approach, called Through Surface Hardening (TSH) technology, utilizes a low hardenability (LH) steel and induction hardening to create a contoured hardened pattern, similar to a traditional gas carburizing process. In this study, TSH-processed and conventional gas-carburized SAE 8620 fatigue samples were subjected to reverse torsional loading, generating comparative stress to cycle curves. This paper outlines the torsional fatigue performance and metallurgical characteristics of each process type.
