Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic ferrite (duplex) stainless steel and precipitation hardening stainless steel according to the state of the organization. 

In addition, can be divided into components: chromium stainless steel, chromium nickel stainless steel and chromium, manganese, nitrogen, stainless steel and so on. E-BON the most excellent stainless steel company, which provide you with china Stainless Steel Housewares on sales.

Ferritic stainless steel 
chromium 12% ~ 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and the resistance to chloride stress corrosion is better than other kinds of stainless steel. There are Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 and so on. 

Ferritic stainless steel because of high chromium content, corrosion resistance and oxidation resistance are better, but mechanical properties and technical performance is poor, more used for less acid structure and use as antioxidant steel.

This kind of steel can resist the corrosive atmosphere, nitric acid and saline solution, and high temperature oxidation resistance, low coefficient of thermal expansion and other characteristics, for nitric acid and food factory equipment, but also can be made to work under high temperature parts, such as gas turbine parts etc.. E-BON the stainless steel specialist, Stainless Steel Powder Shaker supplier.
Austenitic stainless steel
Title Chromium more than 18%, but also contains about 8% of nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, corrosion resistant variety of media. Austenitic stainless steel are commonly used brands such as 1Cr18Ni9, 0Cr19Ni9 and so on. 0Cr19Ni9 steel Wc<0.08% steel is labeled as "0". 

This kind of steel contains a lot of Ni and Cr, which makes the steel austenite at room temperature. This kind of steel has plasticity, toughness, weldability, corrosion resistance and no magnetic or weak magnetic properties and good in oxidizing and reducing medium are good corrosion resistance, acid used to make equipment, such as nitric acid resistant containers and equipment corrosion linings, pipelines, equipment parts, also can be used as stainless steel watch the main material of jewelry. Austenitic stainless steel is usually treated by solid solution. 

The steel is heated to 1050~1150 DEG C and then water-cooled or air-cooled to obtain a single phase austenite structure.
