How about eating in a stainless steel bowl?

Question 1: Are stainless steel tableware used well? Stainless steel tableware materials are divided into three grades: 430, 304 (18-8) and 18- 10. 430 stainless steel: Iron+12% or more chromium can prevent oxidation caused by natural factors, so it is called stainless steel. It is code-named 430 in jis, so it is also called 430 stainless steel. However, 430 stainless steel cannot resist oxidation caused by chemicals in the air. 430 stainless steel will still be oxidized (rusted) due to unnatural factors after not being used frequently for a period of time. 18-8 stainless steel: iron+18% chromium +8% nickel, resistant to chemical oxidation. This kind of stainless steel is 304 in jis code, so it is also called 304 stainless steel; 18- 10 stainless steel: but there are more and more chemical components in the air, and even 304 will rust in some seriously polluted places; Therefore, some advanced articles will be made of 10% nickel to make them more durable and corrosion-resistant. This kind of stainless steel is called 18- 10 stainless steel. In the description of some tableware, there is a statement similar to "using 18- 10 the most advanced medical stainless steel material". According to the metallographic structure, stainless steel can be divided into three categories: austenitic stainless steel, ferritic stainless steel and martensitic stainless steel. The main components of stainless steel are iron, chromium and nickel alloy, in addition, it also contains trace elements such as manganese, titanium, cobalt, molybdenum and cadmium, which makes stainless steel stable, stainless and corrosion-resistant. Austenitic stainless steel is not easy to be magnetized because of its special internal molecular structure.

Question 2: Is eating in a stainless steel bowl harmful to your health? Be careful of the heavy metal hazards of stainless steel tableware. Stainless steel tableware generally contains chromium and nickel. Chromium is a material to prevent products from rusting, while nickel is a corrosion-resistant material. If inferior stainless steel tableware is used, or stainless steel tableware is used improperly, it may cause the harm of heavy metals to human health. When buying stainless steel tableware, pay attention to the parameters indicated above. Stainless steel tableware often has three codes: 13-0, 18-0 and 18-8. The number before the code indicates the chromium content, and the number after it indicates the nickel content. In order to prevent the harm of heavy metals such as nickel and chromium to human body, attention should be paid when using stainless steel products: (1) Do not use stainless steel tableware for a long time to hold strong acid or strong alkaline food, so as to avoid the dissolution of metal elements such as chromium and nickel. (2) Do not use stainless steel utensils to decoct Chinese medicine. Because traditional Chinese medicine contains many alkaloids, organic acids and other components, especially under heating conditions, it is difficult to avoid a chemical reaction with it, which will invalidate the medicine and even produce more toxic chemicals. (3) Do not use strong alkali or strong oxidizing chemicals for cleaning.

Question 3: Is it good to eat in a stainless steel bowl? Porcelain bowls are of course good!

Besides iron, stainless steel also contains chromium and nickel, which has strong corrosion resistance. The content of chromium is generally above 13%, and the content of nickel is also around 10%. For example, a stainless steel contains the following elements in addition to iron:

Cr (Cr)17.0% ~19.0%; Nickel 8.0% ~11.0%;

C (carbon) ≤ 0.14%; Silicon content ≤ 0.80%; Mn (manganese) ≤ 2.00%;

P (phosphorus) ≤ 0.035%; Sulfur content ≤0.03%.

Hope to adopt!

Question 4: Is frequent use of stainless steel tableware harmful to human health? There are many kinds of stainless steel by composition, some are high-quality and some are inferior, such as 303 stainless steel bars. Some are even "stainless iron". The most suitable stainless steel for kitchen utensils is 18/ 10 medical stainless steel (containing 18% chromium and 10% nickel). This stainless steel is bright, food-grade, safe and stable, and has strong corrosion resistance. Almost all foreign famous stainless steel pot pots and pans are made of this material. In particular, 18/ 10 stainless steel kitchenware was invented in Germany. For example, Ssangyong made in Shanghai and Supor, a domestic brand, also use this kind of steel. Japanese zebra stainless steel tableware is also 18/ 10 stainless steel. Slightly inferior, it is 18/8 stainless steel (domestic label 304 stainless steel bar). For example, a locked pot or a Tupperware pot. These high-quality stainless steel pot are safe in medicine and food. If they are used every day, they will certainly be harmless to health. Note that the stainless steel container with the best antirust performance is not completely rust-free. It is not suitable for storing electrolyte for a long time. For example, it is not suitable for making salt jars, vinegar jars and overnight vegetable soup. Stainless steel containers may be corroded into pits. As for low-grade stainless steel, you can't use it like this. So, please don't worry about friends who use stainless steel tableware every day. As long as the stainless steel tableware you choose meets the national standards.

Question 5: How about eating in a stainless steel bowl? Once the surface of stainless steel bowl is corroded or scratched, the harmful components of steel will come out.

Question 6: Do you eat with stainless steel pot Bowl every day? Stainless steel tableware contains heavy metals such as tax, chromium and nickel. Because I don't know whether the manufacturer uses food-grade stainless steel, I should pay attention to it when choosing it.

Question 7: Is the stainless steel bowl easy to use? A: There are many kinds of tableware used in daily life, such as eating bowls. In today's diversified products, there are many choices for a eating bowl, including ceramic bowls, imitation porcelain bowls, wooden bowls and stainless steel bowls. A friend may ask, how about eating in a stainless steel bowl? This article will introduce this.

In fact, many tableware are not inferior products as long as the quality reaches the standard, so it is no problem to make achievements in ordinary life and it will not cause harm to the human body. The same is true of stainless steel bowls. The key point is how to choose a stainless steel bowl with good quality.

Generally speaking, stainless steel tableware is often marked with three codes: 13-0, 18-0 and 18-8. The number before the code indicates the chromium content, and the number after the code indicates the nickel content. The higher the nickel content, the better the quality, such as "18". The code font should be printed on the finished stainless steel tableware. If there is no similar code, it is a fake bowl and should not be used as tableware.

Question 8: How about eating in an iron bowl? As long as it doesn't rust, iron can be supplemented, just like using an iron pan in a wok.
