Chloride stress corrosion:

One of the most significant forms of stress corrosion which concerns the nuclear organization is chloride stress corrosion. Chloride stress corrosion is a category of intergranular corrosion and occurs in austenitic stainless steel under tensile stress within the presence of chloride ions, oxygen, and high temperature.

It is thought to begin along with chromium carbide deposits along grain boundaries which leave the metal open to corrosion. This form of corrosion is controlled through maintaining low chloride ion and oxygen content within the environment and use of low carbon steels.
