Known as a form of corrosion that could cause catastrophic failures of critical assets even under low residual tensile stress for a susceptible metallic material, stress corrosion cracking (SCC) is difficult to predict and identify. SCC is a failure mechanism that requires the simultaneous action of a corrosive media and a sustained tensile stress. In some cases, SCC may occur in combination with hydrogen embrittlement.
To evaluate SCC or Hydrogen embrittlement, our team will use different chemical attack and condition as per ASTM G30, ASTM G103 or ASTM G36, and will perform Slow Strain Rate Testing (SSRT) according to different standards (e. g. NACE TM0198, NACE TM0111, ASTM G129 or ISO 7539-7).
