Nowadays, stainless steel plates have become a metal composite material that people cannot leave in their daily work, such as clothing, food, housing, and transportation. These raw materials can be used to make electrical equipment, as well as daily necessities. Therefore, their use is very common, and these raw materials, like their names, can exceed the excellent corrosion resistance effect during their application period. Stainless steel plates can resist the erosion of air, and when exposed to water vapor and some weakly alkaline chemicals, the raw materials can remain unchanged, and the surface layer is not easily covered by clothing. I think many metal composite materials, although widely used, can undergo significant changes when exposed to strong acids and alkalis in natural environments, which limits the specific application of this raw material. Stainless steel plates are not prone to this problem during their application period, as they can still maintain their condition for a long time after touching the compound.
