Susceptibility of Gun Steels to Stress Corrosion Cracking

Abstract

Precracked cantilever beam specimens extracted from specific gun tubes were subjected to a constant load in various environments to determine fracture times. Specimens exhibited stress corrosion susceptibility in 3% NaCl, distilled water and 100% RH air, with 3% NaCl being the most degrading environment. Variations in susceptibility appeared on a tube to tube basis and were related to the temper embrittled condition of the tube. Additional tests in distilled water, varying yield strength material, showed that fracture time was decreased and crack growth rates increased as the yield strength was increased.
