Resistance of Variously Heat-Treated Samples of Ni-Mo and Si-Cr-Mo-Zr Steels to Perforation by Fragment-Simulating Projeectiles

Abstract

At the request of the Office, Chief of Ordnance, tests have recently been conducted to determine the resistance of variously heat-treated samples of nickel-molybdenum and silicon-chromium-molybdenum-zirconium steels to perforation by fragment-simulating projectiles. Although the resistance of the as-quenched samples of the silicon-chromium-molybdenum-zirconium steel as well as that of samples of the same composition drawn at 300 F. was considerably better than that of the other samples tested, it did not begin to compare with the resistance provided by an equivalent weight of Hadfield manganese steel under impact of the same types of projectiles.
