Definition - What does Stress Corrosion mean?
Stress corrosion refers to the degradation and/or rust formation of a given metal surface in an electrochemical fluid environment due to the metal being subjected to tensile forces in residual or direct form.
Stress corrosion erodes the microscopic granular composition of a metal surface, often causing the surface to crack and disintegrate due to significant tensile stresses.
Corrosionpedia explains Stress Corrosion
Metal modification processes such as welding, cold or hot bending, machining, or grinding can create residual stresses in a metal, which accelerate stress corrosion. Certain metals such as carbon steel and copper alloys are more prone to stress corrosion in corresponding electrochemical environments.
