Which is better, 304 or 316 stainless steel vacuum flask?

The main materials of the stainless steel vacuum flask are 201 stainless steel, 304 stainless steel and 316 stainless steel. The most common stainless steel vacuum flask in our lives should be 304 stainless steel. Today I mainly talk about the difference between 304 stainless steel and 316 stainless steel. Which one is better?

First of all, we must start with their classification. Although both are made of austenitic stainless steel, 304 stainless steel is made of food grade stainless steel, and 316 stainless steel is medical grade stainless steel, so in terms of grade, 316 stainless steel is higher than 304 stainless steel. ,

In terms of performance, 316 stainless steel has better corrosion resistance and heat resistance than 304 stainless steel, and the insulation performance of 316 stainless steel will be better.

Therefore, if one of the 304 or 316 insulation cups is better, then the 316 insulation cup must be better than the 304 insulation cup.

The vacuum flask produced by Dongguan Zhanyi Commodity Technology Co., Ltd. is made of sufficient materials and exquisite workmanship. The material adheres to the combination of food-grade 304 stainless steel inside and outside, or a combination of 304 stainless steel outside and 316 stainless steel. It keeps heat for 18 hours and keeps cold for 24 hours. The entire production process adopts AQL2.0 inspection standard, which is far higher than peer standards.
