Afternoon

Im wondering if anyone could tell me how heat resistant Stainless steel is? Im thinking of putting it behind a wood burning stove...

Any thoughts

Thanks

my pots and pans are made of stainless steel. regularly use the frypan in the oven at 240 celcius...

Good point... never thought about that - Doh!

Anything combustible behind it may give you problems, so be aware that wood burns.

There are different grades of stainless, some are more heat resistant than others, such as 321ti, had added titanium, making it more heat restant than 304 for instance.

In your application, its not going to be that important, just about any grade would do. 304 being one of the more common, and cheaper grades is what id be looking at.

Any thin sheet will bend and warp if it's unevenly heated like you intend. It must be thick enough to heat fairly evenly and withstand the thermal stresses.

No, I don't know how thick you should get. Sorry!

How big will the bit be?

Very thin sheet like 1mm will move...
Certain polishes will make it show more than other.

Stainless steel is used for manufacturing processing equipment run at high temperatures of anywhere up to 150C. You have no problem with the heat resistance of the steel plate itself.
However, ss conducts heat so you need to look at what you have behind it ie what it's screwed to, to be sure it isn't inflammable.
I once built a stone barbeque and made a stainless steel fire box and a stainless steel grill for the steaks. The fire box was removable so that I could empty the ashes. There was no problem. It withstood the charcoal fire in the grate/box for years, and barbequing was every weekend - I lived in a hot climate then. The temperature of a charcoal fire has to be in the upper hundreds Celsius. I sold the house eventually, but I expect the barbeque is still there doing steaks...

Stainless should be little different to other steels, the advantage may be that its naturally shiny surface will reflect the radiant heat.

It would be best if you fixed the plate with spacers between it and the wall to offer some insulation.
