3. Can stainless steel 304 make tea?
4, 304 steel will not make tea.
1. You can safely make tea in 304 stainless steel cups.
2. Making tea in stainless steel cups will not bring harm to human health.
3. Tea leaves are nearly neutral, with low ionic strength and almost no corrosiveness, and it is even more impossible to corrode stainless steel cups in a short time.
4. Although stainless steel contains chromium, the state has strict standards for stainless steel used in catering containers, so even if there is chromium precipitation in regular stainless steel cups, it is far from harmful to human health.
5.304 steel has a chromium content of 18% and a nickel content of 8%, which has the corrosion resistance and rust resistance of stainless steel utensils, so stainless steel products made of 304 steel can be safely used for making tea.
6. Stainless steel is the abbreviation of stainless acid-resistant steel, and steel or stainless steel resistant to weak corrosive media such as air, steam and water is called stainless steel.
7. The steel resistant to chemical corrosion media (acid, alkali, salt and other chemical corrosion) is called acid-resistant steel.
8. Due to different chemical compositions, their corrosion resistance is also different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid-resistant steel is generally stainless.
9. The term stainless steel refers not only to one kind of stainless steel, but to 100 kinds of industrial stainless steel, and each stainless steel developed has good performance in its specific application field.
10. The key to success is to find out the purpose first, and then determine the correct steel grade.
1 1. There are usually only six kinds of steel related to the application field of building structures.
12. Both contain 17 ~ 22% chromium, and the better steel also contains nickel.
13. Adding molybdenum can further improve the atmospheric corrosiveness, especially the corrosion resistance to chlorine-containing atmosphere.
