Abstract : Specimens receiving cold-working treatments of 0, 2, 5, 10, 20, and 50% were given 8 hour precipitation hardening treatments at 900F and subsequently subjected to stress levels of 80% of yield in a 3.5w/o NaCl at ambient temperature. An alternate wet/dry test was used to simulate actual service conditions. These tests were conducted until failure occurred or a minimum of 720 hourtest time limit had elapsed. A 720 hour test time was considered sufficient to establish the degree of stress corrosion cracking susceptibility. A more severe test was performed on a small number of specimens to determine if crack initiation was a factor in stress corrosion cracking. (Author)
