A high antibacterial austenitic stainless steel used in sanitary equipment

Abstract

The invention aims to provide an austenitic stainless steel material having the high antibacterial property and applied to bathroom devices, and a preparation method thereof. The austenitic stainlesssteel material has the function of effectively resisting high-concentration bacteria under the solution treatment and aging heat treatment states, and the bacterial and microbial corrosion risks caused during using of austenitic stainless steel are lowered remarkably, wherein the concentration is larger than (4-5)*10<6> CFU / mL. The chemical components of the stainless steel comprise 18.0-20.0 of Cr, 8.0-10.5 of Ni, 2.0-4.0 of Cu, 0.5-2.0 of Ga, 0.1-0.16 of N, 0.03 or the less of C, 0.75 or the less of Si, 2.0 or the less of Mn, 0.045 or the less of P, 0.03 or the less of S and the balance Fe.The austenitic stainless steel having the high antibacterial property can be widely applied to bathroom device materials containing high-concentration bacteria, wherein the bathroom device materials particularly are part devices such as a water pipe, a faucet, a shower, a door frame, a storing frame and a multi-groove water tank in the bathroom devices.

Description

technical field [0001] The invention relates to the technical field of austenitic stainless steel materials, in particular to an austenitic stainless steel with high antibacterial performance applied to sanitary equipment materials and a preparation method thereof. Background technique [0002] Modern sanitary equipment has widely used stainless steel as the material of parts. The advantages of this type of material are elegant appearance, good corrosion resistance, simple processing and easy forming. At the same time, its closed function can also prevent liquid from infiltrating or seeping out. Now it has been widely used in water pipes, showers, storage racks, holding rods, door frames and other parts or appliances in bathroom equipment. However, with the improvement of people's living standards, the health management of antibacterial, antibacterial and antiviral has become an issue of great concern in today's society. Microbes, even after external wiping or internal clea...

Problems solved by technology

Therefore, it is necessary to use antibacterial functional 304LN-Cu austenitic stainless steel for the building environment containing bacteria and microorganisms. However, due to the high concentration of bacteria in the application environment of some sanitary equipment, it is limited by the current antibacterial functional stainless steel. It is an effective way to provide an austenitic stainless steel with high antibacterial performance and its preparation method
