SUS304 is a stainless steel type designed by the Japanese standard JIS G4303, which is suitable for production of various components. Its main components are 18% chromium and 8% nickel, and the content of manganese, phosphorous, sulfur, silicon and other elements is relatively low. This makes it easy to process and maintain its corrosion resistance. It is widely used in food processing equipment and medical supplies. This article will mainly introduce the application field and working principle of SUS304 stainless steel.

Application Field of SUS304

SUS304 stainless steel is widely used in kitchen equipment and medical equipment due to its good corrosion resistance and rust preventive performance. In addition, it can also be used in architectural and decorative purposes. SUS304 can be used in door covers, decorative screws, handrails, windows and interior decoration. For example, SUS304 is often used to make street lamps, tourist signs and outdoor benches.

SUS304 stainless steel also has the ability of automobile manufacturing. It is mainly used in exhaust pipes and mufflers of automobiles and can also be used to make automobiles with strong corrosion resistance and strong impact resistance. Some engine covers are also made of SUS304 stainless steel.

Moreover, it can also be used in food processing, dairy products and beverage production. Food processing equipment can be made of SUS304 stainless steel, because it has good corrosion resistance and rust-resisting performance, and it is very easy to clean. It can also be used to make parts of chemical containers, such as chemical tanks and other processing equipment.

The Working Principle of SUS304

SUS304 stainless steel is an iron and chromium alloy with a chromium content of more than 18%. In the presence of oxygen, chromium forms an invisible and anti-corrosive film on the metal surface, which can effectively prevent further corrosion of stainless steel. Therefore, SUS304 can resist corrosion and rust without any protective coating.

SUS304 stainless steel has good oxidation resistance. When heated in the temperature range of 800-1500 °C, it will form an oxide film on the surface to protect the core of stainless steel. In addition, it has good strength and toughness and can maintain good ductility at temperatures below –40 ° C. In general, SUS304 has high temperature oxidation, no stress corrosion cracking, high strength, low thermal expansion coefficient, good formability and excellent machinability.

Conclusion

Generally speaking, SUS304 stainless steel is widely used in many areas, such as kitchen equipment, medical equipment, automobile manufacture, food processing and chemical container manufacturing. In addition, it is characterized by its good oxidation resistance, corrosion resistance and rust-resistance performance. As a result, it can be used not only in practical applications but also in decorative purposes.
