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.
A protective oxide layer present on the surface of stainless steel determines its corrosion resistance. However this oxide layer is vulnerable to damage under certain conditions, such as in reducing acids, or in certain combustion mechanism having a reduced atmosphere.he duplex stainless steels, on the other hand, are more resistant to stress corrosion cracking (SCC) than austenitic grades. The ferritic grades are free of SCC. It has been found that SCC resistance can be improved in some cases with the application of compressive stress to the material at risk.
