What are the types of stainless steel sheet metal?

2021-01-14 18:45:21

Stainless steel plate is the general name of stainless steel plate and acid resistant steel plate. Stainless steel plate refers to the corrosion resistant steel plate in weak medium such as atmosphere, steam and water, while acid resistant steel plate refers to the corrosion resistant steel plate in chemical corrosive medium such as acid, alkali and salt. Stainless steel plate has a history of more than 90 years since it came out at the beginning of this century. The invention of stainless steel plate is a great achievement in the world metallurgical history. The development of stainless steel plate has laid an important material and technical foundation for the development of modern industry and the progress of science and technology. There are many kinds of stainless steel plates with different properties, which gradually form several categories in the development process.

 

The classification of stainless steel plate is based on different situations and different classification methods.

1. It is classified according to the thickness of stainless steel plate,

There are mainly the following

Thin stainless steel plate - 0.2mm-4mm

Medium thickness stainless steel plate - 4mm-20mm

Thick stainless steel plate - 20mm-60mm

Extra thick stainless steel plate -- 60mm-115mm

2. According to the manufacturing methods and technologies of stainless steel plate, there are two kinds of classification

One is hot pressed stainless steel plate; the other is cold rolled stainless steel plate.

 

According to the structure, it can be divided into four types: martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, austenitic stainless steel plate and austenitic plus ferritic duplex stainless steel plate.

 

According to the main chemical composition or some characteristic elements of steel plate, it can be divided into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate, low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate, etc.

 

According to the performance characteristics and uses of steel plates, they are divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting corrosion resistant stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate, etc. According to the functional characteristics of steel plate, it can be divided into low temperature stainless steel plate, non-magnetic stainless steel plate, free cutting stainless steel plate, superplastic stainless steel plate, etc. Shaanxi hualite Trading Co., Ltd. is mainly engaged in high-quality seamless steel pipe and alloy pipe of Baosteel, Baotou Steel, etc. Youqi is well-known in the industry for its thick wall tubes, special tubes, high-pressure boiler tubes and alloy tubes.

 
At present, the commonly used classification method is based on the characteristics of steel plate structure and chemical composition, as well as the combination of the two. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation hardening stainless steel plate. Or divided into chromium stainless steel plate and nickel stainless steel plate two categories.
