These proportions of chromium must be evenly distributed in the chemical composition of the material to give it the resistance of stainless steel. If this element is present in sufficient quantities in the alloy and if it is exposed to the oxidative effects of acids, alkalis, water, air and other media, a very thin (130 Angstroms), impermeable layer of chromium oxide (CrO) forms on stainless steels, which prevents corrosion and keeps the material rust-free, unlike regular mild or carbon steel. However, stainless steels are very robust and highly resistant to corrosion under regular conditions because they contain, among other things, chromium. Does stainless steel rust?įirst of all, stainless steel can also rust. ![]() In the following text we will now analyse if, when and why stainless steel can corrode and what kind of measures could prevent this. The term "stainless steel" often misleads us and so we mistakenly believe that stainless steel products are not affected by the problem of corrosion under any circumstances and at any time. ![]()
