magnetic stainless steel sheets for short

Resistant stainless steel for short. Specifically refers to a stainless steel or corrosion-resistant steels as stainless steel in the atmosphere , water vapor , fresh water and other weak corrosive medium ; while the resistance to chemical corrosion ( acids, bases, salts and other chemical attack ) of steel called of acid-resistant steel . qiyi magnetic stainless steel sheets in the chemical composition of leaving their corrosion resistance is different from ordinary stainless steel is generally resistant to chemical corrosion, while
Acid-resistant stainless steel generally has sex . In layman's terms , that is not easy to rust stainless steel , in fact, part of the stainless steel , both of stainless steel , but also acid resistance ( corrosion resistance ) . And corrosion resistance of stainless steel is due to its chromium-rich oxide film on the surface ( passivation film ) formation. This stainless steel and corrosion resistance is relative.
The corrosion resistance of stainless steel qiyi magnetic stainless steel the alloying elements contained . Chromium is the corrosion resistance of stainless steel to obtain the basic elements , when the steel contains chromium content reaches about 12% chromium and corrosive effects of oxygen in the steel surface of a thin oxide film ( self-passivating film) , can prevent further corrosion of the steel substrate . In addition to chromium , commonly used alloying elements nickel , molybdenum, titanium , niobium, copper , nitrogen, etc. , in order to meet a variety of uses for stainless steel organization and performance requirements.
