You're checking a vendor datasheet for a produced-water injection pump and google 'carbon steel vs 316 stainless centrifugal pump chloride cracking offshore'. The fluid has 18,000 ppm chlorides at 60 °C, oxygen scavenged, no H2S. What degradation mechanism should dominate your material decision?

Question

Accepted Answer

60 °C is the boundary that catches people. Above roughly 50–60 °C, austenitic grades like 316 become vulnerable to chloride SCC even when oxygen is low and chemistry looks benign. General corrosion of carbon steel is slower here, sulfide mechanisms need H2S, and erosion needs solids that weren't stated.
