Stainless steel's rust resistance and corrosion resistance are due to the chromium rich oxide film (passive film) on its surface. And this kind of rust resistance and corrosion resistance are relative. Generally speaking, stainless steel is not simply rusty steel, not rusty steel!

The results show that the corrosion resistance of steel increases with the increase of chromium content in weak medium such as atmosphere, water and oxidizing medium such as nitric acid. When the chromium content reaches a certain percentage, the corrosion resistance of steel changes abruptly, that is, from easy to not easy to rust, from never corrosion resistance to corrosion resistance.

When the appearance of stainless steel pipe presents brown rust spots (spots), people are greatly surprised: they think that "stainless steel is not rusty, rust is not stainless steel, it may be the steel presents a problem". In fact, this is a one-sided view of the lack of understanding of stainless steel. Stainless steel will rust under certain conditions.

Stainless steel has the ability to resist atmospheric oxidation, that is, rust resistance, as well as the ability to corrode in the medium containing acid, alkali and salt, that is, corrosion resistance. However, the corrosion resistance of the steel varies with its chemical composition, additive condition, service condition and environmental medium type. For example, 304 steel pipe has excellent corrosion resistance in dry and clean atmosphere, but when it is moved to the coastal area, it will soon rust in the sea fog containing a lot of salt; But 316 steel pipe is good. Therefore, not any kind of stainless steel can resist corrosion and rust in any environment.
