ABSTRACT:
High strength alloy steel cartridge cases characterized by very high isotropic yield strength characteristics are produced from high temperature austenitic conditioned materials by subjecting the materials to a substantial one-pass draw operation and thereafter freezing the materials at approximately -100.degree. F. prior to age hardening.
