Because carbon steels are not very highly alloyed, it is not surprising that most grades do not exhibit large differences in atmospheric-corrosion rate. Nevertheless, alloying can make changes in the atmospheric-corrosion rate of carbon steel.
The corrosion resistance of stainless steel depends on the formation of a âpassive surface ï¬lmâ composed of nickel and chromium oxides (Cr 2 0 3 & Ni0). Passivation involves removing free Fe or âtramp Feâ from the stainless steel surface. This is the purpose of Pascal. The nitric acid in Pascal enriches the stainless steel with Cr & Ni. The oxides (Cr 2 0 3 & Ni0) then form and a passive surface now is in place.Steps:1.
