Why do we suggest you choose inner material stainless steel 304 for sublimation vacuum flask, not 201 stainless steel?

 

 

 

Stainless steel 201 vacuum flask only kept warm less than 6-8 hrs, but 304 will be higher than 8 hours and less than 24 hours.


304 stainless steel thermos cup contains more chromium, the surface is matte and it does not easy to rust. And 201 stainless steel is high in manganese, the surface is very bright with dark bright, easy to rust. Therefore, the difference between the two materials is mainly reflected in the different elements contained in the two. The corrosion resistance of 304 stainless steel is better than 201.

Price of  304 is higher than 201. Because 304 stainless steel is stainless steel produced according to American ASTM standards.
