本发明公开了一种食品类加工容器用抗菌不锈钢，属于不锈钢材料技术领域。该不锈钢的化学成分如下(重量％)：C：≤0.08；Si：≤1.00；Mn：≤1.00；P：≤0.04；S：≤0.03；Ni：5.50‑8.50；Cr：15.5‑18.5；Cu：3.0‑5.0；Ga：0.05‑2.0；余量为Fe；该不锈钢经过特殊热处理后，在不锈钢基体中能弥散析出复合抗菌相(富铜相和富镓相)，富镓相的存在能够有效抑制由于不锈钢中铁元素的溶出对细菌细胞代谢能力的促进作用，同时富镓相更易于溶出微量镓离子，它与铜离子一起，具有更强的抗菌功能。本发明所述不锈钢解决了现有食品加工领域中，由于使用不锈钢容器引发的细菌感染问题，可广泛应用于加工领域的消毒设备、蔬菜加工设备、水果加工设备、肉制品加工设备等各类不锈钢容器。

The invention discloses an antibacterial stainless steel for food processing containers, belonging to the technical field of stainless steel materials. The chemical composition of the stainless steel is as follows (weight%): C: ≤ 0.08; Si：≤1.00； Mn：≤1.00； P：≤0.04； S：≤0.03； Ni：5.50‑8.50； Cr：15.5‑18.5； Cu：3.0‑5.0； Ga：0.05‑2.0； The residual is Fe; After special heat treatment, the stainless steel can disperse and precipitate composite antibacterial phases (copper rich phase and gallium rich phase) in the stainless steel matrix. The existence of gallium rich phase can effectively inhibit the promotion of the dissolution of iron in stainless steel on the metabolic capacity of bacterial cells. At the same time, the gallium rich phase is easier to dissolve trace gallium ions. Together with copper ions, it has stronger antibacterial function. The stainless steel solves the problem of bacterial infection caused by the use of stainless steel containers in the existing food processing field, and can be widely used in various stainless steel containers in the processing field, such as disinfection equipment, vegetable processing equipment, fruit processing equipment, meat product processing equipment, etc.
