Description

technical field [0001] The invention relates to a ferritic antibacterial stainless steel for low-chromium copper-containing tableware and a manufacturing method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's awareness of hygiene and health has gradually strengthened, and they have paid more attention to the living environment and quality of life. There are stricter requirements for kitchenware directly related to human food hygiene and safety. After experiencing "SARS" and "bird flu", the domestic market demand for antibacterial materials and antibacterial products has rapidly increased, and consumers have also begun to recognize and accept "antibacterial" products. Due to the good rigidity, corrosion resistance, rust resistance and beautiful appearance quality of stainless steel, stainless steel has been widely used in the food industry, catering service industry and family life. Will h...
