20 1 Is the material water cup good for your health?

1 and 20 1 are not good for human health. 20 1 stainless steel cup is easy to react in water environment to generate magnesium oxide, that is, rust, which will enter the human body through drinking water and easily accumulate in the human liver, which is not good for human health. Therefore, it is best not to use 20 1 stainless steel cups for drinking water for a long time.

2. 20 1 stainless steel generally refers to 20 1 stainless steel and acid-resistant steel, which belongs to high manganese and low nickel stainless steel with low nickel content and poor corrosion resistance. 20 1 is also commonly known as "industrial high manganese steel". If such steel is used to make water cups, people will easily cause cancer after long-term contact with materials with high manganese content and drinking them for a long time. Children's long-term use of such water cups will affect brain development and inhibit physical growth. Severe cases can immediately induce lesions, and such examples have happened many times. Therefore, 20 1 stainless steel must not be used as the production material of stainless steel water cups.
