Abstract

Stress corrosion cracking (SCC) susceptibility of austenitic AISI 304 and AISI 316L stainless steels in 50% CaCl2 solution at 373 K (100°c) under open-circuit corrosion potential was investigated. The stages of SCC were monitored by acoustic emission (AE) and the tests of the AE was high consisting of low amplitude impulses. In the steady state phase the AE activity was low and towards the end of the test it increased with the increasing amplitude of the impulses. It was found that AE allowed a good correlation between AE signals and SCC damage.
