So today I was burning seasoned Ash that started off gassing. Secondaries were being burned off at the top of the stove with the wood gas with the stove top going from 350 to about 450, cat crusing around 950. All well and good. As soon as the flames disappeared in the firebox the cat went to 1350 in about 30 seconds. Stove top went down to 300, single wall pipe 18" above the stove about 200. So obviously the cat took on the job of burning the wood gas without raising the stove top or flue temps. So with this said what is the top end temp for a steel cat ? Anything above 1300 and I get nervous. Thoughts welcomed.
Top temp for a steel cat?

1600 is where the washcoat flattens out, regardless of whether it's on steel or ceramic.
When the wash flattens out, the cat doesn't look different to the naked eye, but it has lost a tremendous amount of surface area and has much less exposed catalyst than it did before.
BKVP on Max cat temps
Given that those coil type cat probe thermometers are probably ±200 degrees to start with, 1300 is a good limit to set yourself.

I have the Auber for the cat temp so it's accurate to one degree F. The other temps are with a IR gun. No bimetal thermometers here.
