Abstract
A perforating charge case is made by a process that includes cold forming a material into a shape for the perforating charge case. The cold forming produces additional recrystallization nucleation sites in the material. After the cold forming, the material may be annealed to decrease sizes of grains of the material to improve a ductility of the material to increase fragment sizes of the perforating charge case when an explosive that is placed inside the perforating charge case detonates.
