摘要：The stress corrosion sensitivities of 25Cr2Ni2MoV, 26NiCrMoV10-10 and 30Cr2Ni4MoV low-pressure rotor steels in simulated nuclear steam turbine operation condition were investigated by slow strain rate test (SSRT). Results revealed that the SCC sensitivity of 25Cr2Ni2MoV steel was highest in 3.5wt.%NaCl solution at 180°C, while the SCC sensitivities of 26NiCrMoV10-10 steel and 30Cr2Ni4MoV steel were similar. The SCC sensitivity of CrNiMoV steam turbine rotor steels could be decreased by the decline of mechanical strength. ? 2019 Trans Tech Publications Ltd, Switzerland.
