Corrosion behavior of turbine blade 1Crl3 steel in simulated initial condensate water with SO4 2−, Cl−, NO3 −, F− and other impurity anions was studied by electrochemical testing and microscopic characterization (SEM, EDS, XRD and so on). The results showed that the acid corrosion of 1Cr13 steel was not caused by low molecular weight organic acids alone, but rather as a result of the combined effect of impurity anions and low molecular weight organic acid. The degree of corrosion had a great relationship with the type and concentration of a...
