(1) 304 is a common stainless steel that contains more than 18% chromium and more than 8% nickel. Many kettles and tea strainers are made of this material. The density of 304 stainless steel is 7.93g/cm3, which can High temperature resistance of 800°C, widely used in food and medical industries as food grade stainless steel.
(2) 316 stainless steel has added Mo (molybdenum) element, its corrosion resistance and high temperature resistance have been greatly improved compared with 304 stainless steel, and it can withstand high temperatures of 1200-1300 ° C. It is mainly used in the food industry and surgical equipment . Another advantage of 316 stainless steel is that there is no thermal expansion and contraction.
Generally speaking, both 304 and 316 belong to food-grade stainless steel, and it is relatively safe to use them to make children's thermos pots. However, the corrosion resistance and high temperature resistance of 316 stainless steel are better than 304 stainless steel, so when choosing a thermos cup for children, 316 stainless steel can be given priority, after all, safety comes first.
