Towards understanding the effect of surface residual stress on atmospheric chloride-induced stress corrosion cracking of austenitic stainless steels
Source abstract
Abstract
The effect of residual stress on the propensity for Atmospheric Chloride-Induced Stress Corrosion Cracking (AISCC) of austenitic Types 304L and 316L stainless steel was investigated. The surface residual stress of welded ASTM G58 plates was characterised prior to and after AISCC exposure. The magnitude of residual stress required to initiate AISCC and the associated Stress Intensity Factors (SIF) for the propagation of AISCC were evaluated. AISCC was observed in Type 304L after 4-weeks of ambient temperature exposure and in Type 316L after 17-weeks. An estimated SIF for crack initiation in Type 304L in the range of 1.2 to 3 MPa√m for surface cracks (KIsur) and 1 to 2.4 MPa√m for subsurface cracks (KIsub ) was obtained.
