Stress corrosion cracking (SCC) is a failure process which occurs in metals and alloys caused by the combined action of a specific environment and tensile stress. Tensile stresses may be externally applied or be present as residual stresses in the metal resulting from various heat treatment and fabrication processes. The specific environments which will cause SCC are dependent on the material under consideration. For example, carbon steels are susceptible to SCC in environments containing nitrate (NO3−)⁠, and hydroxide (OH-) ions, while high strength steels are usually prone to hydrogen stress cracking in environments high in hydrogen ion concentrations.
