Since I used mild steel flanges with the 321SS tubing, I was not able to go with the full 321SS annealing. The temperatures for that process are around 2100F of which would have turned the mild steel flange to butter once it cooled back down (it would have annealed the steel so much that it would have lost a lot of its rigidity). If you make the part from full 321SS though, you can anneal the part at ~2100F, which will pull the metal back into solution and eliminate any chromium carbide precipitation. The part will have excellent high-temperature strength, low corrosion, and be a lot less inclined to crack. Unfortunately I could not go for the full annealing because of the mild steel; a fact I was unaware of until after the manifolds were assembled. The place I used was Suncoast Heat Treatments. Their address is: Suncoast 4704 W. South Ave Tampa, FL 33614 Their number is: (813) 870-1510 I paid about $110 for the treatment for both manifolds. Just make sure that you let them know what materials you have used to construct them and they will be able to steer you in the direction of which treatment you should use. Good luck!
