The corrosion resistance and heat resistance of 3 16 stainless steel will be higher because of the addition of molybdenum. Generally, the high temperature resistance can reach 1200~ 1300 degrees, and it can be used freely even under very harsh conditions. However, the high temperature resistance of 304 stainless steel is only 800 degrees. Even if the safety performance is good, the vacuum flask of 3 16 stainless steel is slightly better.
Matters needing attention in selecting thermos cup
First, buy through formal channels and try to choose products of well-known brands. Consumers should pay attention to check whether the instructions, labels and product certificates are complete when purchasing, so as to avoid buying "three no products".
Second, check whether the goods are marked with material type and material composition, such as austenitic SUS304 stainless steel, SUS3 16 stainless steel or "Stainless steel 06Cr 19Ni 10".
