In fact, if stainless steel products that meet the relevant national standards in China are used, the migration level of manganese will not cause health damage. Therefore, in GB 9684-20 1 1 Stainless Steel Products as National Standards for Food Safety, the migration of manganese is not quantified, but only the migration of lead, chromium, nickel, cadmium and arsenic is quantified.
Stainless steel is a good material for household appliances and tableware, which has the advantages of durability, easy cleaning and high temperature resistance. 304 and 430 steels are widely used in China. Generally, 430 stainless steel is mainly used as food processing tools, abrasives and tableware, and 304 stainless steel is often used to produce small kitchen appliances. This is in line with national standards, and it is safe to use such standard steel for household appliances and tableware.
