safe!! top barrel temps

looking for some input on what would be a good safe temperature to run a rocket stove for the top of barrel surface temperature??
I have a non mass rocket stove built out of refractories and a 55 gal drum, I am getting top of barrel surface temps at around 830 degrees F, will the barrel stand up to these temps
this stove is cooking hot!!!
thanks

That sounds about par for the course for the barrel top. Some people have said they regularly get temperatures of 1000F or more, though you really don't want it to get hotter than that on a regular basis.

thanks ,what is a safe temp to run for the metal barrel to hold up on top?

Up to about 1000F will make little to no difference in longevity, while over 1000 when it starts to glow, the hotter it gets the more likely it is to suffer over time.

we go to 1000 F  to heat the house up fast but then run it at say 650 to 800 or so most of the time.  that's the top of the barrel of course.
