Pitting Corrosion Of 410 Stainless Steel In Hcl Solutions, Paul D. Krell
Pitting Corrosion Of 410 Stainless Steel In Hcl Solutions, Paul D. Krell
Williams Honors College, Honors Research Projects
410 stainless steel (SS) is a material used in HCl services, such as distillation column trays in oil refineries. Unlike other alloys, however, the oil refining industry lacks a good reference for the corrosion rate of 410 SS at the varying HCl concentrations and temperatures the material might experience as trays in crude unit distillation columns. The goal of this project is to fill that knowledge gap. The corrosion behavior of 410 SS in HCl environments of pH 0.50, 1.25, 2.25, 3.25, and 4.25 at temperatures of 38, 52, 79, and 93°C was investigated using several methods.
