Abstract:
Forged parts and billets of AISI 4340, H11 tool steel, and 9 and 18 nickel alloy steels were evaluated for susceptibility to stress corrosion cracking SCC by an alternate immersion test. The alloys were prepared by the consumable electrode-vacuum melt practice and were heat treated as test specimens to strengths in the range from 263,000 to 290,000 psi. Polished specimens were alternately immersed in a 5 NaCl solution while sustaining a load equivalent to 75 of the ultimate strength.
