Production Feasibility Study for 5-Inch and 8-Inch Cast Steel Projectiles.
Abstract
This study was conducted to determine the feasibility of manufacturing Navy projectiles using casting technology and to establish the cost effectiveness of cast projectiles. Processes were developed using graphite molds with selected areas sand coated that produced high quality five- and eight-inch projectiles. Except for method of manufacture, the cast projectiles met the drawing requirements for projectiles previously furnished as forgings and the physical characteristics were very reproducible. The cast projectiles withstood the proof pressure gun environment and were equivalent to the forged projectiles in ballistic performance. Fragments from the cast projectiles retained a higher velocity than the forged projectiles due to improved fragment shape. Cost estimates for volume production of projectiles using the techniques developed indicate possible cost reduction of 25% on the 5 in/38 caliber projectiles and of 50% on the 8-Inch Mark 25 projectiles.
