Abstract

The influence of parameters of a thermo-mechanical rolling process on corrosion properties of materials 316L and Alloy 825 was studied by means of the DL-EPR-method and a conventional corrosion test. Prior to polarization measurements, optimization of the DL-EPR-method was conducted. SEM was used to characterize microstructure and type of attack before and after corrosion testing. A strong correlation between annual corrosion rates and DL-EPR-test results was obtained. Due to the low tendency of both alloys to form corrosion-promoting precipitates, the applicable range of process parameters for both alloys is large and the fabrication process in general is not critical.
