Why are stainless steel water cups made of 201 stainless steel called poisonous water cups by the media?

There are more and more water cup brands on the market, and there are more and more varieties of stainless steel water cups. Most of these water cups use 304 stainless steel or 316 stainless steel, but there are also some unscrupulous merchants who use 201 stainless steel, which the media calls poisonous water cups. Why are water cups made of 201 stainless steel considered poisonous water cups?
304 stainless steel and 316 stainless steel are both internationally certified food-grade materials. Using such stainless steel to process water cups will not cause harm to the human body and is safer and more environmentally friendly.
201 stainless steel generally refers to the general name of 201 stainless steel and acid-resistant steel. It is a high-manganese and low-nickel stainless steel with low nickel content and poor corrosion resistance. 201 is also commonly known as “industrial high manganese steel”. If such steel is used to make water cups, when the water comes into contact with materials with high manganese content for a long time, it will easily cause cancer if people drink it for a long time. If children use such water cups for a long time, it will affect brain development and inhibit body growth. Severe cases will induce lesions immediately. Such examples have happened many times. Therefore, 201 stainless steel can never be used as a material for the production of stainless steel water cups.
