A detailed study is made of the mechanical properties of 81MM pearlitic malleable cast iron projectile bodies, using a precise method for measuring elongation of tensile specimens. A critical analysis is made of the minimum percentage elongation requirement as an acceptance criterion. A high degree of inhomogeneity is found with respect to percentage elongation. Recommendations are made to eliminate the percentage elongation requirement, replace with other material characteristics. Author
