Fire place liner
 
I have to put a liner in a fire place, what steel would be the best to use?

Thick.

Sorry, that might come across a bit harsh. But anything that is not gold plated
expensive really will all perform similarly. Thicker is better.

Now if you can swing it 316 stainless will last longer. 302/303/304 only slightly
better than mild steel.

Inconel would be the best but yeah you ain't gonna buy that shit.

How thick are we talking?

Unlike wimmen, thicker is better, but I would try to go with 1/4".

The question is this for daily use or occasional hey the wife wants a nice cozy atmosphere 2-4 time a winter...

We watch the fireplace channel on TV.

Can you find some Corten ?
My thought is, that most of the time, it's at room temp, and all oils/paint have been burned off, so that's when the rusting happens.

Corten is just HSLA steel, it will not hold up any better than mild steel to
this kind of heat.

I wasn't thinking about the heat, rather the rusting when cool.

Corten rusts, look at shipping containers.

Is concrete or brick an option? You'd never see steel in an open fireplace over here. (Unless it's a back boiler or a gas/electric pretend fireplace)
