What is stainless steel circle?

The corrosion resistance of stainless steel circles mainly depends on their alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure, which plays a major role in the chromium element. Chromium has high chemical stability, can form a passivation film on the steel surface, make the metal isolated from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. The corrosion resistance decreases after the passivation film is destroyed.
