1. The anti-rust principle of stainless steel

There are so many varieties of stainless steel that there are too many to stew in one pot. The dazzling variety of industrial stainless steels has good performance in various fields. The principle that stainless steel does not rust is very simple. The main reason is that the steel contains chromium, and there is an oxide film called "passivation film" on the surface of the steel. The oxide film is extremely thin and almost transparent to the naked eye. If the oxide film is damaged by other factors, the chromium in the steel and the oxygen in the medium will regenerate a passive film, which acts as a shelter for the steel. A variety of alloying elements can improve the corrosion resistance of stainless steel.

2. Matters needing attention when wiping stainless steel

Alcohol is the first choice when wiping stainless steel products. It is easier to wipe the grease on stainless steel with alcohol. Gently wipe for about three or four minutes to wipe off the grease. Remember to wash off the alcohol with clean water after wiping. If it is a relatively "stubborn" stain, you can use baking soda to wipe it off. Finally, remember to rinse it off with clean water. Remember, in the process of wiping stainless steel, never wipe with hard objects such as steel wire balls. However, the use of too hard objects will cause serious scratches on the surface of the stainless steel.
