1 304 stainless steel is a general stainless steel material. High temperature resistance is also good, and the general temperature limit is less than 650℃. 304 stainless steel has excellent corrosion resistance and intergranular corrosion resistance.
2.3 16 stainless steel, 18Cr- 12Ni-2.5Mo has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength due to the addition of Mo, and can be used in harsh conditions; Excellent work hardening (no magnetism).
3, 304 and 3 16 are austenitic stainless steels, but the difference is that 3 16 adds 2% more molybdenum. The corrosion resistance of 3 16 is better than that of 304. The price is about 20% more expensive.
304 and 3 16 stainless steel are all food-grade stainless steel, which has certain safety performance, but 3 16 stainless steel has better corrosion resistance and high temperature resistance than 304 stainless steel, so when choosing a thermos cup for children, you can choose 3 16 stainless steel.
The following thermos cup is made of 3 16 stainless steel, with humanized design and lovely appearance. Choosing a thermos for your baby depends not only on the price, but also on the performance material.
