What are the classifications of stainless steel plates?

Stainless steel sheets are generally a general term for stainless steel sheets and acid-resistant steel sheets. The stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam, and water, and the acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemical etching agents such as acid, alkali, and salt. Stainless steel plates have been around since the beginning of this century and have been around for more than 90 years. The invention of stainless steel plate is a major achievement in the history of metallurgy in the world. The development of stainless steel plate has laid an important material and technical foundation for the development of modern industry and scientific and technological progress. There are many types of steel plates in stainless steel plates, and their properties are different. It has gradually formed several categories during the development process.

 

According to the structure of the organization, it is divided into four categories: Markov stainless steel plate (including precipitation hardened stainless steel plate), ferritic stainless steel plate, austenitic stainless steel plate and austenitic and ferrite bidirectional stainless steel plate.

 

According to the main chemical composition in the steel plate or some characteristic elements in the steel plate, it is classified into chrome stainless steel plate, chrome nickel stainless steel plate, chrome nickel molybdenum stainless steel plate, low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate and the like.

 

According to the performance characteristics and application classification of steel plates, it is divided into nitric acid resistant stainless steel plates, sulfuric acid resistant stainless steel plates, pitting resistant stainless steel plates, stress corrosion resistant stainless steel plates, high strength stainless steel plates, etc. Classified according to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, non-magnetic stainless steel plate, free cutting stainless steel plate, super plastic stainless steel plate and so on.

 

At present, the commonly used classification method is classified according to the structural characteristics of the steel plate and the chemical composition characteristics of the steel plate and the combination of the two. Generally, it is divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate or precipitation hardened stainless steel plate. Or divided into two categories of chrome stainless steel and nickel stainless steel.
