What is Failure Analysis of Type 204 Tubing about?

The document analyzes a failure of condenser tubes made from Type 204 stainless steel. Metallographic analysis revealed the parent material was highly sensitized with carbide precipitation along grain boundaries, depleting chromium and compromising corrosion resistance. Salt spray, intergranular corrosion, and stress corrosion cracking tests showed the material was susceptible to premature failure from sensitization. Residual stress measurements indicated internal stresses likely exacerbated the failure.
