The acid and corrosion resistance of 1 and 3 16 stainless steel is better than that of 304 stainless steel.

2.3 16 stainless steel is a stainless steel material containing 2% to 3% molybdenum, which has better corrosion resistance than 304 stainless steel.

The corrosion resistance and heat resistance of 3.3 16 stainless steel will be higher due to the addition of molybdenum. The high temperature resistance can reach 1200 to 1300 degrees, and it can also be used under very harsh conditions. But the high temperature resistance of 304 stainless steel is only 800 degrees. Even if the safety performance is good, the 3 16 stainless steel thermos cup is slightly better.
