Why does stainless steel rust also?
People will become very surprising when they see the brown spots on the surface of the stainless steel tubes, for they think the stainless steel won’t rust, or ,they will not to be called stainless steel. And there must be something wrong with the steel. In fact, it’ a unilateral attitude toward steel. They will also rust under some conditions Stainless steel can resist oxidation and corrosion in conditions of acid/alkali/salt due to its capability of antirust and antisepsis. And the corrosion resistance can be various depend on the changes of its chemical composing, mutual influence, using conditions and environment. Let’s take tube 304 as an example. This kind of material can perform well in the clean dry atmosphere. But when to be placed in the coastal areas where the air contains a lot of salt, it will rust soon. And conversely, the tube 316 will perform well in such kind of atmosphere. So, here comes the conclusion, which is stainless steel will rust and be eroded under some condi
