General Corrosion

General corrosion can be described as a corrosion reaction that takes place uniformly over the surface of the material, thereby causing a general thinning of the component and an eventual failure of the material through wall loss. This is most common kind of corrosion observed in most steels. This section contains reports addressing tests and material assessments for general corrosion.

Select Report to read more     Corrosion Study of a Sour Water System Carbon Steel and Type 304 stainless steel samples were exposed in thirteen corrosion tests conducted in solutions (with varying pH, oxygen content, SO2 content, and chloride ion content) in a simulated sour water solution produced in the laboratory. Corrosion rates were calculated, and U-bends were examined for stress-corrosion cracking.   Read more         This report is available for download to corporate users only at this time and will be soon made available for individual purchase. Corrosion in Oleum Under Fluid Flow Conditions Corrosion of 309 stainless steels having 0.07, 0.10, and 0.14 percent carbon as evaluated under simulated fluid flow conditions in high temperature oleum. Electrochemical tests indicated that the corrosion rates of 309 stainless steels, regardless of the carbon content, did not change significantly with the rotating speed under the test conditions examines. The corrosion rate was shown to increase slightly with temperature from 100 - 200 C but, remained less than 12 mpy at temperatures as high a...   Read more         This report is available for download to corporate users only at this time and will be soon made available for individual purchase.
