[Steam-engine] Stainless vs. Sch 80

[Ken Majeski]

Well... Another thing you may want to consider is with stainless if you have 
even a minor leak or weap it will never rust joint. Where with steel it will 
soon rust joint to never leak again.

I don't even know if stainless would even make code for steam boilers. Of 
course in your state it wouldn't matter...

I worried about the nipple between the boiler and water column on my Little 
Case for years and finally replaced it. Turns out it was a schedule 80 Brass 
nipple from the factory. This is also against our code... But if I knew it 
was brass I would have left it.... A simple magnet test would have proved 
what it was... But by the time I found out I had it already cut in half... 
:(
