1. Harm of nickel to human body: Austenitic stainless steel contains a certain proportion of nickel. Although nickel is an essential trace element for human body, excessive intake of nickel may have a negative impact on human health.
2. Harm of chromium to human body: Chromium in austenitic stainless steel is the main source of its corrosion resistance, but high chromium content may also cause harm to human body. Chromate is a common industrial chemical, and long-term exposure to high concentration chromate environment may lead to chromium poisoning.
3. Release of nickel and chromium: Nickel and chromium elements in austenitic stainless steel may be released under certain circumstances, causing harm to human body.
4. Stainless steel scratches and bacterial growth: Austenitic stainless steel has a smooth surface, but scratches will inevitably appear after long-term use. These scratches may become breeding grounds for bacteria, thus increasing the risk of cross-contamination of food. When using austenitic stainless steel products, we should pay attention to keep the surface clean and sanitary to avoid bacterial growth.
5. Other elements in stainless steel: Austenitic stainless steel also contains molybdenum, manganese and titanium. The effects of the intake of these elements on human health are not completely clear. Excessive intake of these elements may cause certain harm to the human body. When using austenitic stainless steel products, attention should be paid to proper intake to avoid excessive intake.
