Is it possible to hot roll steel sheet of 0.8 mm thick ?

Depends on the end use whether it is "good for anything". It might be good as feed the annealing and rolling for tin sheet.

That would fall between the standard steel sheet metal gauges of 21 and 22

21ga =.836 mm

22ga =.759mm

Perhaps a standard gauge would suit your purposes.

Hello,

For us people that are no longer "imperial", 0.8mm is a very common thickness in steels and non-ferrous material for electrical connections and such.

I believe that his challenge will be "how wide" does he want the sheet metal to be? In the past, our supplier was limited to around 1.8m wide for continuous roll for the tolerances on that thickness. Our local supplier has sheet (1.2m x 2.4m) in 0.8, 1.0 and 1.2mm on the shelf, though these are "bog standard" steel with no surface protection.

If he was to source from the U.S.A., then he might need to consider whether one of those "standard" sizes would fit his component tolerances.

Anything is <...possible...>; how likely it is that one would find an economical source of it in the sizes and quantities needed is the true unknown.

Chart below shows thickness above and below 0.8mm. I'd be surprised if you can't get 0.8mm if you want exactly that. Whether it's made by hot rolling I don't know offhand.
