Effect of cathodic potential on stress corrosion cracking behavior of 21Cr2NiMo steel in simulated seawater

This study aims at providing systematically insights to clarify the impact of cathodic polarization on the stress corrosion cracking (SCC) behavior of 21Cr2NiMo steel. Slow-strain-rate tensile tests demonstrated that 21Cr2NiMo steel is highly sensitive to hydrogen embrittlement at strong cathodic po...
