![]() ![]() If the surface is never cleaned, cleaned too infrequently or not cleaned properly, rust can also form underneath longer termed dirt that has not been removed. In addition to the factors mentioned above, contamination during or after processing respectively during or after installation is one of the main factors for corrosion. However, this can lead to visual changes or optical impairments on certain aesthetic surfaces.ĭamage to the protective layer and subsequent contamination is also possible during processing and fabricating, if steel tools or "conterminated" uncleaned stainless steel tools or other objects come into contact with the surface of the stainless steel. Such contact corrosion can be removed with agents specially designed for cleaning such contamination on stainless steel. These can stick to the stainless surface, which then leads to small sources of corrosion in form of specks or small spots. When working with stainless steel materials and products, it is important to ensure that they do not come into contact with any ordinary steel.įor example, when working in the construction industry, strict care must be taken to ensure that no particles of the construction steel (for instance when cutting reinforcements) come into contact with stainless steel surfaces (for example the one of façade elements). Therefore, "freshly treated" surfaces can be particularly susceptible to corrosion and careful reworking and maintenance of these areas is necessary.Īnother circumstance in which rust can occur on stainless steel is possible contact with conventional carbon steel or low-alloy steel. Many cases of rust on the surface of stainless steel are caused by damage to the protective layer of chromium oxide.ĭuring the processing of the material or the production of stainless steel products, damage to the protective layer is very often caused by thermal and/or mechanical stress (e.g. Corrosion (rust) thus forms on stainless steel surfaces when they are exposed to an aggressive load and there is not enough chromium to create and maintain the necessary oxide layer. 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. Take good care of your watch now, and it will be a treasure forever.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. ![]() Use a watch box for long-term storage, and avoid high temperature heat, cold, and humidity, as they will corrode your watch or break it. Many watches have been destroyed by mold, mildew, and corrosion because they were tucked away in a damp, dark box or storage cabinet for years before their value was realized. The cleaning won’t make a difference of your wrist watch if you don’t store them properly. Spray glass cleaner on a soft cloth, and wipe down the watch face, case and bracelet to refresh the shine. Use a hair dryer on a low-heat setting to quickly dry the watch case.Be mindful of how much pressure you apply, as a heavy hand can cause unwanted scratches. Use a damp, clean toothbrush to get into the corners of the stainless-steel watch case or bracelet.In a pinch, a clean dish towel or t-shirt hem will work just fine, but likely won’t remove as much grime as a finer, softer cloth. You can use paper towel for this, but a microfiber or chamois cloth is recommended. Start by wiping down the watch with a soft cloth to remove initial layers of dirt, dust or grime.Therefore you need to maintain your watches even it is stainless steel. ![]()
