| Dec 7, 2018 at 2:30 | comment | added | whatsisname | @nielsnielsen: so, you downvoted and then reiterated several of the points I made? Makes a lot of sense. | |

| Nov 26, 2018 at 22:48 | comment | added | user608672 | How can stainless steal be cheaper than plastic? Plastic is lighter weight, can be durable depending on what kind you buy, cheaper to manufacture and is also corrosion resistant. | |
| Nov 26, 2018 at 18:28 | comment | added | niels nielsen | stainless steel is significantly more difficult to machine, shape and form than either plastic or nonstainless grades of steel. It is also significantly more expensive than nonstainless. It gets used in food service because of its corrosion resistance and specifically in thermos bottles because it is unbreakable. | |

| Nov 26, 2018 at 17:46 | comment | added | Jon Custer | Stainless steel is, perhaps surprisingly (given the question) not a particularly good thermal (or electrical) conductor compared with, say, copper. Its strength really helps a thermos survive (many of us older folks remember the sickening sound made by a glass thermos bottle upon impacting the floor). | |
