What is antibacterial stainless steel materials ?

Antibacterial Stainless Steel - Antibacterial stainless steel with copper and silver

The antibacterial of antibacterial stainless steel mainly uses the copper rich phase. The use of copper (Cu) ion sterilization has a long history. Since 1761, Schulthees used copper sulfate to prevent and control the fishy black disease of wheat, it has been more than 200 years of history. In 1885, the French Milharde successfully developed the famous sterilization function of the Bordeaux containing Cu ion liquid, solved the French Bordeaux manor grapes suffered from the crisis of pests and diseases for years, followed by the emergence of many varieties of Cu ion bactericide, creating an era of Cu ion bactericide application. Cu is a common alloying element in steel and other types of alloy. Adding Cu can improve the strength and uniform corrosion resistance of steel, and improve the cold deformation processing performance of steel, which creates conditions for the development of new medical copper materials with antibacterial function through alloying.

Industry application

Household appliance industry is the pioneer to promote the industrialization of antibacterial products, Haier and other famous domestic backbone enterprises, Electrolux, Siemens and other international brand manufacturers, has become a very active antibacterial product brand in the market.

In the tableware industry, the Institute of Metal Research and development of Chinese Academy of Sciences has developed all-material stainless steel antibacterial tableware, the whole is made of antibacterial stainless steel raw materials. At present, all-material antibacterial stainless steel has been applied to ASSTEC antibacterial tableware, with durable and excellent antibacterial properties, the killing rate of Escherichia coli, Staphylococcus aureus, etc. is more than 99%, and it still maintains good antibacterial properties after surface wear.

In the building materials industry, Shengda floor, Baosuo PVC pipe, Vian PP-R aluminum plastic, Xianyang Pipe aluminum plastic pipe, new super steel plastic pipe, and only Rodin, Marco Polo tile, Na Mei paint, Libon paint, PU polyyeast wood coatings, nitro (NC) wood coatings have been developed and marketed antibacterial products.

Alloy type antibacterial stainless steel

Alloy type antibacterial stainless steel refers to the addition of antibacterial metal elements in the process of smelting conventional stainless steel, and then special antibacterial heat treatment to obtain good antibacterial properties of stainless steel. This stainless steel has excellent antibacterial properties after wear.


Broad-spectrum antibacterial: killing rate of Escherichia coli, staphylococcus aureus and so on are above 99%;

Antibacterial durability: Good antibacterial performance after surface wear;

Human safety: antibacterial stainless steel in toxicity and human safety fully meet the national technical standards;

Properties of stainless steel: mechanical, corrosion resistance, hot and cold processing, welding and other properties of the original stainless steel.
