Abstract
Stress corrosion behavior of FeCrAl ferrite stainless steel under PWR water deviation condition was investigated by slow strain rate tensile (SSRT) tests. The results show that FeCrAl ferrite stainless steel is subject to stress corrosion cracking (SCC) at strain rate of 2×10-7s-1, with the co-exist of Cu2+ and Cl- in water. SCC of FeCrAl ferrite stainless steel in high temperature water containing Cu2+ and Cl- is considered to result from pitting corrosion.
