Effects of Processing Variables on Erosion of Gun Tubes

Abstract

A reduction in silicon with an associated increase in molybdenum is known to increase the wear life of gun steel when fired under subscale firing conditions. However, when this same material is employed in a full scale firing test utilizing the 105-mm M-68 gun tube, the wear life of the tube, as measured at the origin of rifling (i.e. OR), remains the same regardless of silicon and molybdenum content. A few inches beyond the OR (27 inches from the rear face of the tube and beyond), the results of the full scale firing test agree with the results of the subscale firing tests, in that the low silicon steel exhibits a lower erosion rate than for a normal gun steel composition.
