Training on Detecting Intergranular Stress Corrosion Cracking (IGSCC) Using Advanced Ultrasonic Array Technology

Intergranular Stress Corrosion Cracking (IGSCC) is a type of failure that occurs along the grain boundaries in metals, typically in materials under tensile stress in corrosive environments. This form of cracking requires three primary factors: the presence of tensile stress, a corrosive environment, and a material that is susceptible to this type of damage. IGSCC is most commonly seen in stainless steels, especially when exposed to corrosive agents like chlorides or high-temperature water. Industries such as nuclear power plants, chemical processing, and marine structures are particularly vulnerable to IGSCC due to the harsh environmental conditions they operate in. Preventing IGSCC involves selecting materials with greater resistance to this type of corrosion, minimizing the tensile stress on components, and controlling the environmental factors that contribute to corrosion. Detection of IGSCC is typically performed through non-destructive testing methods, such as ultrasonic testing or visual inspections, which allow for early identification and mitigation of this critical issue.
