A 12 in long steel combustor would expand ~ 0.22 inches from zero to 1500 °C. This combustor approached melting. Does a magnet stick to this combustor?
It should have been made of stainless steel which melts around the same temperature 1500 °C. Expansion for stainless would be about 0.3 inches for a 1500 °C rise.
1500 °C is about 2700 °F.
I love the odd coefficient of expansion units - in/in °C. A mixture of US units and metric.

A magnet does stick to the cat.
Normally, a magnet will not be attracted to stainless. Perhaps your cat was made from steel.
On the units thing: Couldn't decide if the Vermont Castings in the picture was made by the Canadian VC company or the American VC company. So I had to use units from both. To be fair and all that.
I've got to do some reading on why stainless does not attract a magnet. It's one of the thing I didn't like when we got a stainless steel fridge, and my wife loved.
There is mention of Paris, Kentucky on the stove back - but I can't tell if that's where it was made. I suspect they would be using the US units there. Definitely got a kick out of the mixed units, though.
Of the top of my head I recall that stainless is not a ferrous metal, specifically, it lacks sufficient iron content for magnetic attraction. I can't remember the various components of stainless of the top of my head.
