201 stainless steel itself is not toxic.
It is easy to rust and is harmful to health after rust. The content of Mn in 201 material is very high, which will cause damage to the healthy element ions precipitation in the process of dressing food and heating. The corrosion resistance of 201 stainless steel is not good, and it is generally used in the environment of low
201 stainless steel belongs to the low nickel stainless steel, its anti-rust performance is poor, generally used for contact with the environment is relatively dry products, and the tableware generally use 304, this stainless steel belongs to the high nickel stainless steel, strong anti-rust performance, and tableware is often in
contact with water, oil and salt and so on, so 201 can not eat tableware.
Choose and buy stainless steel products, it is recommended to choose 304 steel, stainless steel utensils are safe, mainly the heavy metal migration problem. Generally speaking, the 304 steel commonly used in the market is less chromium migration.
Stainless steel products should pay attention to the following points:
1, containing salt, acid components of food should not be used in stainless steel products long-term sheng fang. Stainless steel has good stability and corrosion resistance, but it does not mean that it will not be corroded or rusted.
If for a long time in stainless steel products storage salt, vinegar, will lead to its surface rust or appear "trachoma", so it is not recommended that the family use stainless steel products storage such items.
2, do not use stainless steel products Fried herbs. Chinese herbal medicine composition is complex, mostly contains a variety of alkaloids, organic acids. When heated, it is easy to react with some of the components in stainless steel, so that the efficacy of the drug is decreased, and even some of the more toxic
substances may be generated.
3, not empty burning stainless steel products. Stainless steel products than iron, aluminum products, low thermal conductivity, heat conduction is relatively slow, empty burning will cause cooker surface chrome-plating layer aging, off.
