2. These two kinds of stainless steel materials are nationally recognized food-grade stainless steel with international standards. Whether it is a 304 stainless steel thermos cup or a 3 16 stainless steel thermos cup, the material safety is completely guaranteed. However, the comprehensive performance of 3 16 stainless steel is still much higher than that of 304 stainless steel, so you can consider buying 3 16 vacuum flask when choosing vacuum flask.
3.304 Stainless steel thermos cup is only used for drinking healthy tea leaves such as red dates and medlar or soaking, and cannot be used for drinking beverages containing acid and alkali substances such as milk and coffee, because the acid and alkali substances in milk and coffee may cause corrosion or chemical reaction to the inner container; 3 16 stainless steel can completely prevent the corrosion of acid-base beverages such as milk and coffee because of its high strength and corrosion resistance.
4,316 is better. Both 304 and 3 16 stainless steels are food-grade stainless steels with certain safety performance, but 3 16 stainless steel has better corrosion resistance and high temperature resistance than 304 stainless steel. Choosing a thermos for your baby depends not only on the price, but also on the performance material.
5.3 16 stainless steel 3 16 stainless steel is a kind of stainless steel. Due to the addition of Mo element, its corrosion resistance and high temperature strength have been greatly improved. High temperature resistance can reach 1200- 1300 degrees, and it can be used under harsh cool conditions.
6.3 16 stainless steel is also the main user of food industry and surgical equipment. Another feature of 3 16 stainless steel is that it does not expand when heated and contract when cooled.
