DTIC ADA139728: High Fragmentation Steel Production Process

Two heats of HF-1 steel which were purchased and metallurgically characterized in the previous phase of this project were used to determine the efforts of vendor and/or cooling method (used to produce the steel) on the production of the M549 projectile warhead metal parts. Parameters investigated included mult-parting, forging, rough-machining and nosing. The study included the design and development of tooling and forging and machining parameters in attempt at a cost-effective manufacturing process.
