What kinds of stainless steel can be used to make tableware

Although stainless steel has many advantages, not all stainless steel can be used to make tableware. Stainless steel can also be divided into many different types. Each type of stainless steel has different functions, especially the stainless steel used to make tableware has strict requirements and regulations.
After being made into tableware, stainless steel will directly contact with food. If it does not meet the standard, it is likely to harm our health. Therefore, our country is also conducive to strict regulations on food and stainless steel in direct contact with food.
At present, only stainless steel conforming to the national mandatory standard GB4806.9-2016 National Food Safety Standard Metallic Materials and Products for Food Contact can be called food grade stainless steel on the market. In this standard, the upper limit of migration of arsenic, cadmium, lead, chromium and nickel in stainless steel products under specific measurement methods is restricted.
The familiar 304 stainless steel, even if it is a food grade stainless steel, can be used to make ordinary prescription dispersers. In addition, there is 316 stainless steel. The nickel content of 316 stainless steel is higher than 304, so it has better corrosion resistance. In addition, other elements are added in the production process. Therefore, this 316 stainless steel is mainly used in the food industry or surgical equipment.
When purchasing stainless steel tableware or other kitchenware, we must see whether 304 or 316 is marked on it. Other types of stainless steel must not be purchased, especially low-quality stainless steel, which may contain some heavy metal elements, which is also very harmful to our health.
