Let’s discuss about steel rust, this article can help you to get informed about steel rusting.
prevent stainless steel from rusting
There are two basic types of stainless steel :
(1) highly corrosion resistant ni-cr austenitic steel
(2) corrosion-resistant ferrite and martensite steel.
Basically, a passivated surface layer of chromium oxide formed on the stainless steel handrail protects the metal from corrosive media in everyday use and the surrounding environment. The resistance of alloys to various chemical solutions is too complex to be fully covered. Extensive testing of most stainless steel alloys in the environment around Europe and the United States has shown that rust and white corrosion products can form on all stainless steel in up to a few years, even on any stainless steel product that was very clean, to begin with.
Many different mechanisms can be involved in the formation of these corrosive products. In some cases, redeposition from the surface of the alloy leaves ions on the surface of the steel. Under appropriate heat and humidity conditions, these ions combine with oxygen and form corrosion products. The formation of iron can lead to rust.
Redeposition of chromium ions leaves behind deposits of chromium oxide, which can produce white spots on polished steel with a rough surface. Of many causes that can lead to rusting of stainless steel is the exposure of the material in oxygen and water, storage conditions like humid areas, polluted and open places, environment with a high level of chlorine and acid rain. The corrosion of stainless steel is caused by redox reaction, which is actually two simultaneous reactions at the same time; reduction and oxidation. Stainless steel and metals undergo the same reaction when they are exposed to the material we discussed before, and a film of brown, reddish substance gets deposited on the surface or material called rust.
Here are some ways to prevent stainless steel from rusting
Welding is the area where stainless steel handrails are most likely to “rust” or soiled, causing iron contamination. Similarly, the use of non-stainless steel processing and processing equipment in the manufacture, cutting, or processing of stainless steel is also a common source of pollution. Non-metallic contact materials and vacuum lifting equipment should be used to avoid process contamination. Working in a “mixed metal” manufacturing plant can lead to such decay if cleaning measures are not taken.
Do not cut stainless steel handrails or deposit non-stainless steel grinding debris on stainless steel articles. Once any pollutant gets wet, it can lead to rust. Once contaminated metal will suffer corrosion, and may even be damaged and broken, this is the metal reaction between two metals
If stainless steel handrails and stainless steel railings are cleaned regularly, they will not form any corrosion products for many years. This highlights the importance of periodically cleaning stainless steel railings. Handling or manufacturing stainless steel on the equipment should be avoided, and tools that are also used for non-stainless steel should be used.
In industry, physical rust prevention and chemical passivation rust prevention are often used to prevent stainless steel from rusting; The so-called physical rust is simply in the surface of stainless steel coated with a layer of rust oil to protect stainless steel does not rust, this method is relatively simple and practical low cost, the use of stainless steel itself corrosion resistance plus rust oil protection stainless steel body nature can ensure that the long-term rust; Chemical rust protection is the use of passivating liquid to the surface of stainless steel passivating a protective film, relatively speaking, the operation process is more complicated still need to consider the early treatment and environmental protection issues.
