Stainless steel plates came out in the early 20th century and have a history of more than a century. Stainless steel plate has many advantages, such as: smooth surface, high plasticity, toughness and mechanical strength, corrosion resistance of acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not rust-free. Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate. Stainless steel plate refers to steel plate resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to steel plate resistant to corrosion by chemical corrosive media such as acid, alkali and salt. Since stainless steel plates came out at 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 technological progress..

There are many kinds of stainless steel plates and steel plates with different properties. It has gradually formed several categories in 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 austenitic plus ferritic duplex stainless steel plate; according to the steel plate The main chemical composition or some characteristic elements in the steel plate are classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate, etc. The commonly used classification method is based on the structural characteristics of the steel plate and the chemical composition of the steel plate, as well as the combination of the two. . It has a wide range of uses. Typical uses: heat exchangers for pulp and papermaking equipment, mechanical equipment, dyeing equipment, film washing equipment, pipelines, exterior materials for buildings in coastal areas, etc.

There are many advantages of stainless steel plates. Let's introduce the corrosion resistance, high temperature oxidation resistance and physical properties of stainless steel plates.

(1) Corrosion resistance. The stainless steel plate has the ability to resist general corrosion similar to the unstable nickel-chromium alloy 304. Long-term heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require materials to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.

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

(3) Physical properties. The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the film heat dissipation coefficient, scale and metal surface condition. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory Stainless Steel provides technical standards for stainless steel plates. Stainless steel plates have high-strength stainless steel plates with excellent corrosion resistance, bending workability, toughness of welding parts, and excellent stamping performance of welding parts and their manufacturing methods.
