Stress corrosion cracking (SCC) is the cracking induced from the combined influence of tensile stress and a corrosive environment. The impact of SCC on a material usually falls between dry cracking and the fatigue threshold of that material. The required tensile stresses may be in the form of directly applied stresses or in the form of residual stresses, one example might be of an aircraft component. The problem itself can be quite complex. The situation with buried pipelines is a good example of such complexity.

Stress crack corrosion is a problem in many industries, mostly due to expansion and contraction, enhanced by leachable chlorides.

Control Sample Typical Stress Cracking within 100 hours of exposure per ASTM C 692

 

Treated Sample No Cracking after 100 hours exposure per ASTM C 692

Stress-relief cracking, also called post-weld heat treatment cracking, occurs when susceptible alloys are subjected to thermal stress relief after welding to reduce residual stresses and improve toughness. Stress-relief cracking occurs only in metals that can precipitation-harden during such elevated-temperature exposure; it usually occurs at stress raisers, is intergranular in nature, and is generally observed in the coarse-grained region of the weld heat affected zone.
