Metallurgical Examination of Hull Bow Casting, Serial Number 134 for Medium Tank M4, Manufactured by American Steel Foundries

Abstract

The object of this study was to determine if the interior ballistic properties of the casting are traceable to unsatisfactory metallurgical characteristics. It was conclude that: (1) The poor ballistic properties of the case hull front section are due to a combination of low hardness and poor impact properties resulting from incomplete quench hardening. (2) The incomplete quench hardening is traceable to the use of a steel of insufficient hardenability to adequately quench harden through the section thickness.
