Stress corrosion cracking (SCC) is difficult to predict and identify, and can lead to catastrophic failure, often without any prior warning. Element’s stress corrosion cracking testing can help to evaluate the susceptibility of metallic materials to cracking. We quickly determine the size and scope before the failure occurs, avoiding high industrial costs and safety hazards.


What is Stress Corrosion Cracking and why is Testing Important?

Stress corrosion cracking (SCC) is the unexpected sudden failure of standard ductile materials when exposed to the combined effects of sustained tensile stress and corrosion. It can occur with static externally applied loads and residual stresses from welding, forming, machining, grinding, physical damage, heat treatment, and operating pressures. As SCC often develops rapidly, without prior warning, and can lead to catastrophic failure, it is crucial to test for potential issues before they occur.

Early Detection and Prevention

Stress corrosion often develops rapidly in a structure. It’s difficult to predict and can lead to unexpected failures. Stress corrosion cracking testing with Element identifies significant threats such as external and internal corrosion, manufacturing defects, welding and fabrication defects, equipment failures, and incorrect operations. Our testing detects these risks early, preventing costly expenses, safety hazards, and damage to the environment and your company’s reputation.
