Abstract:

The 155-mm M107 projectile was tested at Scranton Army Ammunition Plant at reduced forging temperatures to determine the minimum acceptable forging temperature. During the pilot study, projectiles were forged in experimental groups of 50 each at five furnace temperatures, in decrements of 37.8 C 100 F - starting at the baseline temperature of 1,204 C 2,200 F and ending at 982 C 1,800 F. During production evaluation, 7,539 projectiles were forged without incident at the minimum acceptable forging temperature established in the pilot study namely, 1,093 C 2,000 F. From a baseline tonnage of approximately 5.3 MN 600 tons, forging tonnage increased linearly by approximately 890 kN 100 tons per temperature decrement.
