1. Basic Properties of Austenitic Stainless Steel

Austenitic stainless steel is a type of stainless steel that contains 18% to 24% chromium and 10% to 14% nickel. The structure of this alloy gives it good mechanical properties and corrosion resistance. The microstructure of austenitic stainless steel is made up of a lattice and a small number of austenite grains, which enhance the material's strength and corrosion resistance.


The microstructure of austenitic stainless steel allows it to maintain good performance even at high temperatures. This characteristic makes it very suitable for the food industry, where high-temperature environments are often encountered.

2. The Importance of the Food Industry

The food industry involves processing, storing, and transporting various kinds of food. These foods need to be treated at high temperatures to ensure their freshness and safety. Materials used in the food industry must have good corrosion resistance and antibacterial properties to prevent food from spoiling or being contaminated.


Austenitic stainless steel, with its excellent corrosion resistance and antibacterial properties, has become the preferred material in the food industry. In addition, it has good hygiene performance, which can effectively prevent the growth of bacteria.

3. Advantages of Austenitic Stainless Steel
The main advantages of austenitic stainless steel include:
  • Corrosion Resistance: Austenitic stainless steel can maintain long-term corrosion resistance in acidic, alkaline, and neutral environments. This makes it very suitable for the food industry, as food may come into contact with various environments during processing and storage.
  • Antibacterial Capability: The microstructure of austenitic stainless steel gives it good self-cleaning ability, which can effectively prevent the growth of bacteria. This makes it an ideal material for the food industry.
  • Hygiene Performance: Austenitic stainless steel, after special chemical treatment, can effectively prevent the growth of bacteria and fungi. This characteristic has led to its wide use in the food industry.
  • Mechanical Properties: Austenitic stainless steel has good toughness and strength, which allows it to withstand various mechanical stresses. This makes it suitable for kitchenware, furniture, and other applications.
