Abstract
An antibacterial stainless austenite steel contains (C (0.01-0.12 wt.%), Ni (8-11 wt.%), Cr (7-22 wt.%), Cu (1.5-2.9 wt.%), Si (0-1 wt.%), Mn (0-2 wt.%) and Fe (the rest), and is characterized by that said Cu in epsilon-Cu phase is uniformly diffused in the basic material. Its advantages are high antibacterial effect to colibacillus and Staphylococcus aureus, high weld performance and surface quality of product and easy polishing.
Description
Technical field: the present invention relates to a kind of anti-bacteria stainless steel, particularly austenite antimicrobial stainless steel.
Background technology: in real life, stainless material is all generally adopted in many fields, as fields such as diet, health to cleaning aseptic having relatively high expectations, if common stainless steel, must be often with the sterilization of methods such as medicine, ray, inconvenience and action time are shorter.Anti-bacteria stainless steel has been arranged now, utilized the sterilization ability of metallic elements such as silver, copper itself to play anti-microbial effect.A kind of anti-bacteria stainless steel is disclosed in patent CN1072732C, this stainless composition constitutes very complicated, various elements are too much, sterilising effect is determined inadequately, and it mainly is a kind of ferritic stainless steel, and welding property is very poor, and it contains Ti simultaneously, make steel be difficult for polishing, surface quality is good inadequately.
Summary of the invention:, the invention provides a kind of composition and constitute simply welding and the good austenite antimicrobial stainless steel of polishing performance at the deficiencies in the prior art.
Except that the trace impurity of allowance, form in the body material of the present invention by the composition of following weight percent,
C is 0.01～0.12, Ni is 8.00～11.00, Cr is 7.00～22.00, Cu is 1.50～2.90, Si≤1.00, Mn≤2.00, and all the other are Fe, and Cu with ε-Cu phase even dispersion in body material.
The present invention is an austenite antimicrobial stainless steel, and component is less, and composition is simple, not only has the traditional performance of common stainless steel, and sterilising effect is more satisfactory, can effectively eliminate the intestinal bacteria and the streptococcus aureus of contact with it.Good welding performance of the present invention, polishing easily, the surface quality height of its goods.
Production of the present invention is also more convenient, adds an amount of elements such as copper in corresponding conventional stainless steel is produced, and carries out corresponding thermal treatment again, can produce anti-bacteria stainless steel.
Embodiment: in the body material except that the trace impurities such as P, S of allowance, composition by following weight percent is formed, C is 0.01～0.08, Ni is 8.00～11.00, Cr is 17.00～22.00, Cu is 1.50～2.50, Si≤1.00, Mn≤2.00, all the other are Fe, and Cu with ε-Cu phase even dispersion in body material.
In each composition element, Ni is a key element of obtaining austenite structure, and Cr and Ni can both improve the erosion resistance of metal, and add-on is bigger.Si can form SiO when high temperature
2Film improves oxidation-resistance, and Mn can remove S, the raising quality of materials, C is the assurance of intensity, Cu is the antimicrobial principal element, must through Overheating Treatment with ε-Cu phase even dispersion in body material.
The stainless steel of present embodiment is made product, throws the back through essence and presses pharmacopeia CMC (B) 44102 and CMC (B) 26003 antibacterial tests, and colibacillary killing rate is reached more than 99.2%, and the killing rate of streptococcus aureus is reached more than 99.95%.When goods have used the long period, anti-microbial property may reduce, and only needing again, polishing can recover germ resistance.
Claims (2)
1, a kind of austenite antimicrobial stainless steel, it is characterized by: in the body material except that the trace impurity of allowance, composition by following weight percent is formed, C is 0.01～0.12, Ni is 8.00～11.00, Cr is 7.00～22.00, Cu is 1.50～2.90, Si≤1.00, Mn≤2.00, all the other are Fe, and Cu with ε-Cu phase even dispersion in body material.
2, austenite antimicrobial stainless steel according to claim 1 is characterized by: by weight percentage, C is 0.01～0.08, Cr is 17.00～22.00, Cu is 1.50～2.50.
