Stress <strong>Corrosion</strong> Cracking • Three conditions required for most common kind – Metal under tensile stress – Dissolved Oxygen – Chloride Ion • Brittle cracks form at the sites of stress • Failure can be fast • Failure can occur at stress loads far below yield strength
Erosion <strong>Corrosion</strong> • Flow removes protective layer • New protective layer forms using up metal • Promoted by – High flow – Turbulent conditions – Particulates in fluid • Concern with feeders in HTS
