There is no problem with stainless steel cups that meet the national standards for boiled water, tea and coffee. It is recommended to use 316 stainless steel cups if conditions permit; it is not recommended to pack carbonated beverages or milk for a long time, because if you encounter strong acids, strong alkalis or salts, the chromium in the stainless steel may be precipitated. If you use a cup to hold acidic beverages for a long time, the cup itself will become prone to rust and corrosion. It is recommended to drink beverages other than boiled water as soon as possible to clean them in time.
I believe everyone is familiar with stainless steel. After all, many things in daily life are made by them. Stainless steel is of good quality and high temperature resistance, and is often used in the production of pots and pans. Careful netizens may find that our water-boiling kettle will have a set of numbers on the inner wall of the pot, some are 304 and some are 316. What does this set of numbers represent? What is the significance of it? The Chinese element corresponding to
1, 304 stainless steel is 0Cr18Ni9; the Chinese element corresponding to 316 stainless steel is 0Cr17Ni12Mo2.
2 and 304 stainless steel are relatively low-priced and are usually used in daily life, such as kettles, chopsticks, etc. The price of 316 stainless steel is relatively high. Although some of it will be used in daily life, most of it is still used in medical or heavy industrial equipment.
3 and 316 are safer and corrosion-resistant than stainless steel cups made of 304.
