An 18Ni (280) maraging steel has been tested in 3.5% NaCl solution under various modes of loading. The most severe condition was plane strain loading of fatigue precracked samples. The severity of stress corrosion cracking (SCC) of unnotched samples decreased in the sequence: plane strain bending, tension, plane stress bending, and torsion. The most consistent explanation for the various observations is that SCC results from hydrogen embrittlement. Under certain circumstances anodic dissolution processes can result in beneficial crack blunting effects rather than SCC failure.
