Description

Stress corrosion susceptibility of Type 304 stainless steel in various concentration of CaCl2 solution has been examined by two types of the slow strain rate technique (SSRT), comparing with time to failure and corrosion potential which had been obtained by the constant load test in the same solution. The SSRT in free corrosion condition and in controlled potential condition was compared. It is concluded that the controlled potential SSRT, the potential of which is simulated to the constant load test, could give more proper index corresponding to time to failure than the conventional type SSRT done in free corrosion condition. But in the lower concentration region below the critical concentration of 25% CaCl2, both type of the SSRT could not cause SCC which had been observed in the constant load test.
