Hongwang’s new antibacterial stainless steel trial production succeeds

As a environmentally friendly material, stainless steel is widely used in various fields such as tableware, kitchenware, medical apparatus and building decoration.. With the social and economic development and the improvement of peoples living standards, the use of healthy and safe stainless steel has become more and more extensive. Since the outbreak of the coronavirus, the research and development of antibacterial stainless steel has become a hot spot in the stainless steel industry

Recently, a new type of antibacterial stainless steel product developed by Hongwang group with independent intellectual property rights was put into trial production. The product has been authoritatively inspected by Guangdong Provincial Microbial Analysis and Testing Center. The abtibacterial rate of common E.coli, klebsiella pneumoniae and other bacteria is over 99%, and it has excellent broad-spectrum antibacterial properties. 

The research  antibacterial stainless steel has a long history. The traditional research direction is mainly adding copper, silver and other alloy elements during the steelmaking process. After special aging solution treatment, a specific copper or silver phase is generated to produce free copper or silver ions enriched on the surface of stainless steel, which destroys the bacterial cell wall and has a bactericidal effect. However, the production cost is high, and the precision of the smelting process is difficult to control, so that the application is difficult to improve.

In the face of the epidemic, Hongwang has made full use of its key technical reserves over the years to accelerate research, development and trial production of antibacterial stainless steel. Through the self-developed stainless steel surface vapor deposition technology and intermediate frequency sputtering ion coating technology, the oxide bacteria composite antibacterial material target is deposited on the stainless steel surface under vacuum. This will integrate the antibacterial film with the stainless steel surface itself, combining the antibacterial property with the corrosion resistance of stainless steel itself, so that the stainless steel has long-lasting high antibacterial performance.


This new production process of antibacterial functional stainless steel not only does not change the surface color and texture of the stainless steel, but also does not affect the mechanical processing performance. At the same time, it has the characteristics of high production efficiency and controllable cost. The products have broad application prospects in various fields, and has important practical significance for effectively preventing the spread of germs, preventing cross-infection, and improving the level of public health.

Hongwang now has the ability to process whloe coils or single sheets of new antibacterial functional stainless steel. The main product width is 1000mm to 1300mm, thickness is 0.3mm to 1.15mm. The single sheet is divided into 4*8 feet, 4*10 feet specifications. And products can be customized according to customer needs.  

The research and development and successful trial production of new antibacterial stainless steel is the representative work of Hongwang“innovative spirit”. In the future, we will continue to focus on stainless steel cold rolling, surface finishing and service areas, continue to promote the development and application of functional stainless steel products.
