A high antibacterial performance austenitic stainless steel used in construction and decoration products

Abstract

The invention aims at providing high-antibacterial-performance austenitic stainless steel applied to building and decoration articles and a preparing method of the high-antibacterial-performance austenitic stainless steel, the high-antibacterial-performance austenitic stainless steel has the effective high-concentration bacterium (>(4-5)*10<6>CFU / mL) resisting function in the state of solid solution and aging heat treatment, and the bacterium microorganism corrosion risks caused during austenitic stainless steel usage are obviously reduced. The stainless steel comprises chemical components including 18.0-19.0 of Cr, 8.0-10.0 of Ni, 1.0-2.0 of Cu, 0.5-1.5 of Ga, 0.1-0.15 of N, smaller than or equal to 0.03 of C, smaller than or equal to 0.75 of Si, smaller than or equal to 2.0 of Mn, smaller than or equal to 0.045 of P, smaller than or equal to 0.03 of S and the balance Fe. The high-antibacterial-performance austenitic stainless steel can be widely applied to building and decoration materials containing high-concentration bacteria, specifically to large-area building and decoration and ornamenting of plants, office buildings, household buildings and the like.

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 building and decorative materials and a preparation method thereof. Background technique [0002] In modern architecture and decoration, some stainless steel materials are used as wall decoration materials in many cases. The advantages of this type of material are that they are beautiful and generous, and have the function of closed waterproof and easy to use. Now they have been widely used in In large-area construction and decoration such as factories, office buildings and household buildings. 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. After long-term use of traditional stainless steel, microorganisms will grow on the surface of stainl...

AI Technical Summary

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 buildings, it is limited by the limitations of 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
