Which is better, ceramics or 3 16?
Ceramic is better. Compared with 3 16 stainless steel liner, the ceramic liner is better, and the ceramic coating is added to the stainless steel liner, which has better heat insulation and corrosion resistance than the uncoated stainless steel liner. Vacuum cups are basically made of stainless steel, but there are many kinds of stainless steel materials, such as 304,316,201and so on.
