Resistance of Various Thicknesses of Hadfield Manganese Steel to Perforation by Various Projectiles
Abstract
As indicated in earlier work at this arsenal variations in the quality of Hadfield manganese steel may well be reflected in the resistance characteristics of the material. Although no metallurgical investigation of the subject samples was made it is apparent from certain discrepancies in the resistance of various samples that the quality of the pieces was not constant. Material of this type of constant good quality would be expected to show an orderly increase in resistance as its thickness increased, and at any one thickness would be expected to exhibit consistent resistance characteristics against any one projectile. The results indicate that the quality of the subject samples is somewhat variable and demonstrate the need of rigid application of Specification AXS-1170 in the procurement of material intended for use as components of armor assemblies.
