304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm ³; Also known as 18/8 stainless steel in the industry, it means containing over 18% chromium and over 8% nickel; High temperature resistance of 800 ℃, with good processing performance and high toughness, widely used in industrial and furniture decoration industries, as well as food and medical industries. However, it should be noted that food grade 304 stainless steel has stricter content indicators compared to ordinary 304 stainless steel.

● Composition: 304 stainless steel, also known as 18/8 stainless steel in the industry, contains over 18% chromium and over 8% nickel. Some food grade 304 stainless steels require a chromium content of 18% and a nickel content of 8%, allowing for fluctuations within a certain range and limiting the content of various heavy metals.

● Physical properties: The density is 7.93g/cm ³, the melting point is 1398-1454, and it has weak magnetism. After cold processing such as stretching and stamping, the magnetism will become stronger.

● Mechanical properties: It has good processing performance and toughness, as well as high tensile strength and hardness. At the same time, it also has good corrosion resistance and heat resistance, and can be used in the temperature range of -196~800.

The application fields of 304 stainless steel are very extensive, including but not limited to the following aspects:

● Industrial and furniture decoration: Due to its excellent comprehensive performance (corrosion resistance and formability), 304 stainless steel is widely used in the production of equipment and components that require these properties. It is also widely used in the construction field, such as doors and windows, handrails, railings, and household items, such as kitchen cabinets, sinks, bathroom products, etc.

● Food and medical industry: 304 stainless steel is also widely used in the food and catering industry, such as making kitchenware. Especially for food grade 304 stainless steel, its content indicators are more stringent, ensuring safety in contact with food. At the same time, it is also used to manufacture medical equipment and devices.

● Automotive parts: 304 stainless steel can also be used to manufacture automotive exhaust systems, fuel pipes, and other components.

The production process of 304 stainless steel mainly includes the following steps:

● Melting manufacturing: Obtaining stainless steel melt through smelting and melting.

● Heat treatment: includes steps such as hot rolling, heat treatment, and annealing to alter its microstructure and physical properties.

● Cold processing: including cold rolling, cold drawing, cold drawing, cold bending, and deep drawing processes, can change the shape, size, and surface quality of stainless steel.

● Surface treatment: In order to improve the appearance and corrosion resistance of stainless steel, surface treatment processes such as polishing, sandblasting, pickling, and electroplating are usually carried out.
