Stainless steel can also be used in medical devices. The corrosion resistance of stainless steel decreases with the increase of carbon content, and most stainless steels have low carbon content, so corrosion will not occur. Tea is brewed with Tieguanyin, Jin Junmei and black tea, and is not suitable for white tea, Longjing tea and Maojian tea. Tea is easy to change color, which affects the taste.
304 steel can resist corrosion of sulfuric acid, phosphoric acid, formic acid and urea. , suitable for general water, control gas, wine, milk, CIP cleaning solution and other occasions. Adding molybdenum on the basis of 304 can significantly improve the intergranular corrosion resistance, oxidative stress corrosion resistance, reduce welding hot cracking tendency and good chloride corrosion resistance of 3 16 steel. Commonly used in pure water, distilled water, medicine, soy sauce, vinegar and other places with high hygiene requirements and moderate corrosiveness. The price of 3 16L is almost twice that of 304.
The correct way to make tea
1. Prepare the tea set: select the appropriate teapot, cups and tea leaves and clean them with hot water.
2. Add tea: put a proper amount of tea into the teapot. Generally speaking, 2 ~ 5g of tea is needed per 100ml of water.
3. Cleaning tea leaves: wash tea leaves with hot water once to remove impurities on the surface of tea leaves.
4. Hot cup: Hot cup with hot water first can increase the temperature of tea soup.
5. Water temperature: Different kinds of tea need different water temperatures. Generally, green tea needs 80~85℃ water, black tea needs 90~95℃ water, and black tea needs 100℃ water. Suitable water temperature can be selected according to different kinds of tea.
6. Soaking time: Different kinds of tea need different soaking time. Generally, it takes 1~2 minutes for green tea, 2~3 minutes for black tea and 3~5 minutes for black tea. Suitable soaking time can be selected according to different kinds of tea.
7. pour tea: pour the brewed tea soup into the cup and keep it uniform. You can adjust the depth of tea soup according to your taste.
