The surface of stainless steel plates is clean, and they have high plasticity, toughness and mechanical strength, as well as resistance to corrosion by acidic, alkaline gases, solutions and other media. It is an alloy steel that is difficult to rust, but it is not absolutely rust-free. Stainless steel plates refer to steel plates that are resistant to weak media such as the atmosphere, steam, and water. Acid-resistant steel plates refer to steel plates that are resistant to chemical corrosive media such as acids, alkalis, and salts. Since the20Since the beginning of the century, stainless steel plates have a history of more than a century.

　　Stainless steel plates are generally called stainless steel plates and acid-resistant steel plates. At the beginning of this century, the development of stainless steel plates laid an important material and technological foundation for the development of modern industry and technological progress. There are various types of stainless steel plates with different properties. During the development process, several major categories have gradually emerged. According to their structure, they can be classified into four types: austenitic stainless steel plates and martensitic stainless steel plates(Including precipitation-hardening stainless steel plates)Ferritic stainless steel plates, austenitic and ferritic duplex stainless steel plates; According to the main chemical components in the steel plate or some characteristic elements in the steel plate, it can be classified into chromium stainless steel plate, chromium-nickel stainless steel plate, chromium-nickel-molybdenum stainless steel plate, as well as low-carbon stainless steel plate, high-molybdenum stainless steel plate, high-purity stainless steel plate, etc. According to the characteristics and application conditions of steel plates, they can be classified into nitrate-resistant stainless steel plates, sulfate-resistant stainless steel plates, pitting corrosion-resistant stainless steel plates, stress-resistant stainless steel plates, high-strength stainless steel plates, etc. According to the functional characteristics of steel plates, they are classified into low-temperature stainless steel plates, magnetic stainless steel plates, easy-to-cut stainless steel plates, superplastic stainless steel plates, etc. The commonly used classification methods at present are based on the microstructure characteristics of steel plates, the chemical composition characteristics of steel plates, and the combination of the two. It is generally classified into martensitic stainless steel plates, ferritic stainless steel plates, austenitic stainless steel plates, duplex stainless steel plates and precipitation-hardening stainless steel plates, or into chromium stainless steel plates and nickel stainless steel plates. Typical applications: pulp and papermaking equipment, heat exchangers, mechanical equipment, dyeing equipment, film developing equipment, pipelines, exterior materials for buildings in coastal areas, etc.

　　There are two manufacturing methods: hot rolling and cold rolling, including a thickness of0.5.10-885Millimeters and72938Cold-rolled sheet in millimeters and with a thickness of4.5-100Medium and thick plates in millimeters

　　It can withstand oxalic acid and sulfuric acid-Ferric sulfate, nitric acid, nitric acid-Hydrofluoric acid, sulfuric acid-It is resistant to corrosion by various acids such as copper sulfate, phosphoric acid, formic acid and acetic acid, and is widely used in industries such as chemical engineering, food, medicine, papermaking, petroleum and atomic energy, as well as in various parts of buildings, kitchenware, tableware, vehicles and household appliances.

　　To ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel plates meet the requirements, the plates must undergo heat treatment such as annealing, solution treatment and aging treatment before leaving the factory.

　　The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure.
