**Damage Mechanism** & **Risk Level** & **Justification** \\ \hline Metal Loss & low & The material is resistant to general corrosion mechanisms in this operating condition The component is assumed to be exposed to chloride-containing fluids, mists, or solids; also, the temperature is in the susceptible range for external chloride stress corrosion cracking (CLSCC). \\ Metallurgical & low & In this operating temperature, metallurgical changes are not expected. \\ External corrosion & low & The only external concern is external cracking The chance of the presence of lack of fusion, residual stress, and surface defects remaining from the manufacturing process is high. These parameters increase the risk of fatigue due to the fluid-induced vibrations. \\ Fatigue due to Manufacturing defects & High & Manufacturing process is high. These parameters increase the risk of fatigue due to the fluid-induced vibrations. \\ \hline \hline \end{tabular}
