The Recycling and Reclamation of Used Tank Track Pins

Abstract

This investigation was directed at determining the feasibility of recycling used tank track pins. Tank track pins manufactured from SAE 865OH alloy steel bar were tested in bending fatigue thus establishing the fatigue life characteristics of production pins. These pins were quenched and tempered, induction hardened and shot peened during manufacturing. To determine recycleability, several pins were fatigued at various stress levels to approximately 80 percent of their expected life, and reprocessed to the original specifications. After checking for cracks, these pins along with others which received only the reheat treatment, were fatigued to failure. Microhardness, metallographic and surface residual stress measurements were conducted at various stages of testing and reprocessing to observe changes that may occur.
