In life, invisible and unseen germs, mold, has been the cause of flu, gastroenteritis, skin diseases and other series of diseases “culprit”, seriously affecting people’s health.

In recent years, human research to explore how to inhibit and destroy germs, many antibacterial materials, antibacterial products came into being. With the full outbreak of the new crown epidemic, the development of antibacterial industry at home and abroad has shown a new development trend, antibacterial has become the market consumption of new hot spots. In a variety of antibacterial materials, in addition to our daily contact with ceramics, plastics, textiles and other fields, antibacterial stainless steel also joined the “antibacterial war” team, from kitchen utensils and tableware, health care, public facilities and other important areas of effective interception of germs, playing an irreplaceable role.


Antibacterial stainless steel has antibacterial properties because antibacterial steel in the smelting process, the addition of antibacterial properties of the metal element copper, and then through a special casting, forging, rolling and heat treatment process to manufacture. In addition to the mechanical properties and corrosion resistance of ordinary stainless steel, antibacterial steel has excellent antibacterial properties.

Today, we would like to share with you a series of antimicrobial stainless steel products – black skin steel, white skin No.1 steel and cold rolled 2B steel. The series of antibacterial steel is divided into 301Cu, 304Cu two steel grades.


In the chemical composition, antibacterial steel Cr (chromium), Ni (nickel) and other major elements content is comparable to ordinary stainless steel, antibacterial steel additionally added 3.5-4.0% of the metal Cu (copper) elements, which is the main reason why antibacterial steel can achieve the performance of ordinary stainless steel, in addition to the antibacterial properties.


In terms of mechanical properties, through the flexural bending, tensile testing and hardness testing found that the mechanical properties of antibacterial steel and ordinary stainless steel indicators are similar, but the yield strength of antibacterial steel is lower, which is conducive to plastic deformation of cold processing.




The data from the deep-drawing test, cup-convex test and tapered cup test also fully demonstrate that the antimicrobial steel has excellent drawing performance and “drawing+expansion” composite forming performance. In terms of corrosion resistance, after salt spray corrosion, pitting corrosion and intergranular corrosion tests, the results show that the antibacterial steel has good corrosion resistance.






The antibacterial steel has been tested by the Institute of Metals, Chinese Academy of Sciences and Guangdong Microbiological Analysis and Testing Center, and the antibacterial rate of both E. coli and Staphylococcus aureus has reached over 99%. After polishing, the antibacterial rate can still reach more than 98%.


In addition, 304Cu antimicrobial stainless steel has been tested by EU RoHs, REACH and German LFGB and meets the requirements of relevant standards.


Antibacterial stainless steel is now widely used in kitchen utensils, decoration and bathroom, medical and health care, public facilities and other fields, such as knives, forks, dishes, garbage cans, faucets, washing machine drums, hospital beds, surgical equipment, fitness equipment, public handrails, etc., are widely used in all walks of life。


Antibacterial stainless steel plate/coil products actively cater to the current health and environmental protection concept, the fulfillment of social responsibility and its own development fully combined, through the strict control of product quality, supporting services layer by layer, reasonable product prices, to provide downstream customers with high-quality antibacterial steel coil, plate, narrow strip, laser cutting products, etc., while meeting the customer grinding, mirror, oil grinding brushed, sheet metal, stamping products and other needs, to help promote antibacterial steel products can be quickly popularized by the public use, with its excellent antibacterial properties, to make a positive contribution to people’s healthy life。
