Properties and applications of stainless steel sheets

Classification of stainless steel plates:

According to the structure, it is divided into four categories: austenitic stainless steel, martensitic stainless steel, ferritic stainless steel and austenitic plus ferritic binocular stainless steel.

According to the main chemical composition in the steel plate or some characteristic elements in the steel plate, it is 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 functional characteristics of steel plates, it is divided into low-temperature stainless steel plates, non-magnetic stainless steel plates, free-cutting stainless steel plates, etc.

Properties of stainless steel plate:

The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free.

Stainless steel plate has the ability to resist general corrosion. Mainly used in high temperature applications, which require strong anti-sensitive materials to prevent intergranular corrosion at lower temperatures.

Stainless steel plates have high temperature oxidation resistance, and the oxidation rate will be affected by inherent factors such as exposure environment and product form.

Stainless steel keeps the surface clean, so it conducts heat better than other metals with higher thermal conductivity. The stainless steel plate is heated to 850-1250°C, and then heat treated at 1°C/s or more. This can be called a high-strength stainless steel plate with a structure containing more than 12% martensite by volume, high strength of more than 730MPa, corrosion resistance and bending processability, and excellent toughness of the welding heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of the welded part.

Application of stainless steel coil:

Automobile industry:

Stainless steel coil not only has strong corrosion resistance, but also has a relatively light weight, and is widely used in the automobile manufacturing industry. This can not only greatly reduce the weight of the vehicle, but also greatly improve the life of the car. In addition, it is more and more widely used in coaches, high-speed rail, subway and so on.

Water storage and transportation industry:

The storage and water transportation equipment made of stainless steel coils is currently recognized as the most hygienic, safest and most efficient water industry equipment.

Construction sector:

Stainless steel coils were first used in the construction field. Decorative panels outside buildings and interior wall decorations are generally made of stainless steel coils, which are durable. Not only can be used as building outsourcing, but also can be manufactured into various decorative plates.

Stainless steel coils are also used in the home appliance manufacturing industry. Stainless steel coils are used in the production of many parts and components of home appliances such as washing machines, televisions, and refrigerators.
