HISC – Automatic Strain Criteria
Hydrogen Induced Stress Cracking (HISC) is a problem that duplex and super duplex material may experience when cathodic protected in seawater. The hydrogen of the seawater may diffuse into the material and may lead to cracking. DNVGL-RP-F112 describes diffusion rates, acceptance criteria for both stress and strain levels. HISC is often one of issues that […]
