Evaluation of a Belt-Cast Austenitic Steel Alloy from Salzgitter Mannesmann Forschung: Effect of Hardness on the Ballistic Resistance against Two 0.30-cal. Projectile Types

Abstract

Representative samples of 5-mm thick, belt-cast, high-manganese austenitic steel were obtained from Salzgitter Mannesmann Forschung, a German steel manufacturing concern. The steel samples were subjected to microstructural and quasi- and high-strain-rate mechanical property characterizations. Additionally, the steel was comparatively evaluated ballistically against 2 types of threats, namely, a 0.30-cal. M2 ball projectile and a fragment-simulating projectile. The evaluation showed that overall, an equivalent thickness rolled homogeneous armor plate performed better than the German steel.
