Usually not. Be careful of the heavy metal hazards of stainless steel tableware. Stainless steel tableware generally contains chromium and nickel. Chromium is a material to prevent products from rusting, while nickel is a corrosion-resistant material. If inferior stainless steel tableware is used, or stainless steel tableware is used improperly, it may cause the harm of heavy metals to human health. When buying stainless steel tableware, pay attention to the parameters indicated above. Stainless steel tableware often has three codes: 13-0, 18-0 and 18-8. The number before the code indicates the chromium content, and the number after it indicates the nickel content. In order to prevent the harm of heavy metals such as nickel and chromium to human body, the following points should be paid attention to when using stainless steel products:

(1) Do not use stainless steel tableware to hold strong acid or strong alkaline food for a long time, so as to avoid the dissolution of metal elements such as chromium and nickel. (2) Do not use stainless steel utensils to decoct Chinese medicine. Because traditional Chinese medicine contains many alkaloids, organic acids and other components, especially under heating conditions, it is difficult to avoid a chemical reaction with it, which will invalidate the medicine and even produce more toxic chemicals.

(3) Do not use strong alkali or strong oxidizing chemicals for cleaning.
