As we all know, stainless steel has good corrosion resistance, beautiful appearance, etc., it is widely used in our life, so stainless steel really does not rust?

When the stainless steel surface of brown rust (point), people great surprise: that "Stainless steel is not rust, the rust is not stainless steel, May be there was a problem in steel." In fact, this is a lack of understanding for stainless steel. Stainless steel will rust under certain conditions.

Stainless steel has good corrosion resistance due to the oxidized layer on the surface. But the ability of resist corrosion is along with the chemical composition of the steel itself, using conditions and environmental medium.
 
For example, in dry indoor environment using 430 stainless steel, the effect is quite good, it has absolutely excellent anti-corrosion ability, but moves it to the waterfront area, will soon rust; while 316 stainless steel is performing well.

Therefore, not any kinds of stainless steel, in any environment corrosion resistant, not rust.

 "Stainless steel" is not just a kind of stainless steel, is more than one hundred kinds of industrial stainless steel, Developed by each stainless steel has good performance in their specific applications.

Now the technology of stainless steel is more and more excellent, the Product performance is higher, the corrosion resistance is stronger, and the stainless steel price is not the same, too.

Stainless steel type should be selected according to the application environment and purpose so as to keep fine appearance and extend the life time, or will cause premature rusting.
