You see this thing? It's hydraulic tubing About 6.5 or 7mm thick.
By the end of the 32 hours burns, it was like puff pastry in the elbow. The metal was about 1 inch thick inside, because of the spalling, and the cyclonic rocket was unusable. The gas bottle started sagging under it's own weight. That's metal heated to the white. You obviously see the spalling. That's not on the oxygen rich side, which creates the spalling usualy. If you don't trust me. Carry on. But please, don't tell me afterwards that your contraption works wonders and such. I know that if you reach the proper temps for a rocket stove of any kind to work properly, steel won't hold.
I can even tell you that i'm killing refractories too. I've had the bricks and refractory tubing in another stove, glowing orange. That's more than 900C°, yep celcius, not farenheit. How long do you think steel could survive at that kind of temp. Seemingly, a rocket can reach 1200C° on a regular basis.
I should have cut that elbow on the cyclonic rocket, to show the world what a rocket can do to metal. But i threw it in the skip before thinking about it.
