What kind of material should be used for the stainless steel water water bottle?

We know that water is an essential item in our daily life. But do you know which material is the most suitable?

SS201: Usually, we use this material on the outside of the bottle because it is not a food-grade material.

SS304: Food-grade material. We typically use this material for the inner liner of stainless steel water bottles.

SS316: Medical-grade material, a high-end material. Usually used for the blade heads of surgical knives. It has a higher specification than 304 stainless steel.
