Stainless steel
Generally speaking, stainless steel is not easy to rust steel, in fact, a part of stainless steel, not only rust, but also acid resistance (corrosion resistance). Stainless steel stainless steel and corrosion resistance is on the surface of chromium rich oxide film (film) formation. This kind of rust and corrosion resistance is relative. E-BON the most excellent stainless steel company, which provide you with stainless steel mule mugs copper mule mugs.

The test shows that the steel in the atmosphere, water and other medium and weak acid oxidizing medium, the corrosion resistance increased with the increase of water content of chromium in steel, when the chromium content reaches a certain percentage, the steel corrosion resistance mutation from rust to rust, corrosion and corrosion resistance to never. There are many methods of classification for stainless steel.

According to the organizational structure of classification at room temperature, a martensitic, Austenitic, Ferritic and duplex stainless steel; according to the classification of the main chemical components, basically can be divided into chromium and chromium nickel stainless steel two systems; by use of minute nitric acid resistant stainless steel, stainless steel, stainless steel corrosion resistance to sulfuric acid and so on, according to the corrosion resistance the type can be divided into stainless steel pitting corrosion, stress corrosion resistant stainless steel, intergranular corrosion resistant stainless steel; according to the features of classification can be divided into non magnetic stainless steel, stainless steel, stainless steel, free cutting low temperature high strength stainless steel and so on.

Because stainless steel has excellent corrosion resistance, formability, compatibility and strong toughness in a wide range of temperature, it has been widely applied in heavy industry, light industry, household goods industry and building decoration industry. E-BON the stainless steel specialist, china Stainless steel manufacturers.

Austenitic stainless steel
A stainless steel having austenitic microstructure at normal temperature. About 18%, Ni 8%~10%, C about 0.1% Cr in steel, with austenite stability. Austenitic chromium nickel stainless steel, including the famous 18Cr-8Ni steel and the high Cr-Ni series steel developed on the basis of increasing Cr and Ni content and adding elements such as Mo, Cu, Si, Nb and Ti. Austenitic stainless steel is nonmagnetic and has high toughness and plasticity, but its strength is low.

It can't be strengthened by phase transformation, and can only be strengthened by cold working. If the elements such as S, Ca, Se, and Te are added, they have good machinability. In addition to corrosion resistant to oxidizing acid medium, such steel can resist corrosion of sulfuric acid, phosphoric acid, acid, acetic acid and urea if it contains Mo, Cu and other elements. If the carbon content in this kind of steel is less than 0.03% or Ti and Ni, the intergranular corrosion resistance of the steel can be significantly improved.

The high silicon austenitic stainless steel concentrated nitric acid would have good corrosion resistance. Austenitic stainless steel has been widely used in all walks of life because of its comprehensive and good comprehensive properties.
