The specific meaning of stainless steel plate

Stainless steel plate is generally the general term for stainless steel plate and acid-resistant steel plate. Stainless steel plates refer to steel plates that are resistant to corrosion by weak media such as atmosphere, steam, and water, while acid-resistant steel plates refer to steel plates that are resistant to corrosion by chemically corrosive media such as acids, alkali, and salts. Stainless steel plates have been around since the beginning of this century. The development of stainless steel plates has laid an important material and technical foundation for the development of modern industry and scientific and technological progress.

There are many types of stainless steel plates with different properties. They have gradually formed several major categories during the development process. According to the organizational structure, it is divided into four categories: austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardened stainless steel plate), ferritic stainless steel plate, and austenite plus ferrite duplex stainless steel plate?

Classified according to the main chemical components 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 performance characteristics and uses of steel plates, they are 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. According to the functional characteristics of steel plates, they are divided into low-temperature stainless steel plates, non-magnetic stainless steel plates, easy-cut stainless steel plates, superplastic stainless steel plates, etc.

It has a wide range of uses. Typical uses: heat exchangers for pulp and papermaking equipment, mechanical equipment, dyeing equipment, film processing equipment, pipelines, exterior materials for buildings in coastal areas, etc.

The density of 304 stainless steel plate is 7.93g/cm3. Austenitic stainless steel generally uses this value. 304 contains chromium (%) 17.00-19.00 and nickel content (%) 8.00-10.00. 304 is equivalent to my country's 0Cr19Ni9 (0Cr18Ni9) stainless steel.

304 stainless steel plate is a versatile stainless steel material with stronger anti-rust performance than 200 series stainless steel materials. It is also better in terms of high temperature resistance.

304 stainless steel plate has excellent stainless corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it was found in experiments that 304 stainless steel plates have strong corrosion resistance in nitric acid below the boiling temperature with a concentration of ≤65%. It also has good corrosion resistance to alkali solutions and most organic and inorganic acids.
