How is stress corrosion generally defined?
Stress corrosion generally refers to the corrosion that occurs in steel after cold working or welding, resulting in residual stresses; this corrosion manifests in the products manufactured as a result of such processing, especially in stainless steel when it comes into contact with chloride ions.
The brittle cracking of stainless steel below its strength limit in specific corrosive environments under static tensile stress is known as stress corrosion cracking. This type of corrosion is highly destructive: it causes tiny pits to form in the parts of stainless steel that are susceptible to corrosion, leading to the development of small cracks that propagate rapidly, resulting in severe damage in a short period of time.
