Some corrections
I was just looking through this thread and realized there are a couple corrections I’d like to make. Ability to edit these posts only lasts about 5 minutes so I have to do it waaaaay down here at the end where virtually no one will see it!
Firstly, I think the factory recommended nitro content was 10% not 15%. Not that it matters now!
Secondly, I had a little trouble bending up some stainless pipe after I wrote this thread and came to find out I wasn’t heating it up enough. Stainless needs to be anealed at over 1000 degrees. This is way brighter than the dull red I mentioned. Bright yellow is what you want, then it will bend like butter. No need to quench - this pipe air quenches.
