Stress corrosion cracking

STRESS CORROSION CRACKING S092

Describes a localized failure caused by tensile stresses in a medium.

Stress corrosion occurs below the metal’s yield point as a result of cyclic application of the stress. This can be a problem in mechanical seals because of their repeated cyclic operation.

Chloride stress corrosion is probably the most common form of corrosion we experience with stainless steel springs and the metal bellows used in some mechanical seals.
