Classification of stainless steel and properties and uses of common models

Stainless steel is the abbreviation of stainless acid -resistant steel. Weak corrosive media such as air, steam, and water or stainless steel types are called stainless steel. "Stainless Steel" is a collective term for more than 100 industrial stainless steel types. Each stainless steel has good performance in its specific application field. With its excellent corrosion resistance and beautiful appearance, the application of stainless steel products in production and life is very wide. The common types of stainless steel are mainly steel types such as 201, 304, 316, 321, and 310s.


Stainless steel is usually divided into: 

1. Ferritic stainless steel: it contains 12%~30% chromium, and its chloride stress corrosion resistance is superior to other types of stainless steel.

2. Austenitic stainless steel: it contains more than 18% chromium, about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can resist corrosion of various mediums.

3. Austenitic -ferrite bilateral stainless steel: also has the advantages of Austenitic and ferrite stainless steel, and has super plasticity.

4. Matrier stainless steel: high strength, but poor plasticity and weldability.

5. Precipsexic hardening stainless steel: It is a genetically tissue or martensite tissue, and stainless steel can be hardened by precipitating hardening.

 

The nature and use of common stainless steel:

201 stainless steel, which has the characteristics of acid resistance, alkali resistance, high density, polishing non -bubbles, and punch -free. It is the production of various cases, straps, and high -quality materials for the bottom cover.

304 stainless steel, as a wide range of steel, has good corrosion resistance, heat resistance, low temperature intensity and mechanical characteristics. The heat processing properties such as stamping and bending are commonly used in the food industry, kitchenware, and home products.

316 Stainless steel, which add molybdenum, has a particularly good corrosion resistance and high temperature strength, which can be used under harsh conditions. Commonly used in marine equipment and chemical industry.

321 Stainless steel, add titanium element to the 304 steel to prevent the crystal industry from corrosion. It is suitable for use at 400 ° C to 900 ° C, and is often used for medical appliances, ship components, and atomic energy industry.

310S stainless steel, contains high chromium and nickel, has good antioxidant, corrosion resistance, high temperature resistance, can be continuously operated at high temperatures, often used in boilers, exhaust machines, heat switches, etc.

Stainless steel needs to be used in various industries after multiple processes such as ironmaking, steelmaking, continuous casting, hot rolling, cold rolling, pickling, annealing, etc. Glimpse Technology is a high-tech enterprise focusing on metallurgical equipment. With its expertise and experience in metallurgical projects, it can provide customers with a full set of equipment and technical solutions for stainless steel manufacturers.
