[Steam-engine] Stainless vs. Sch 80

[Orrin Iseminger]

In my humble opinion, stainless steel would be overkill.  Furthermore, any
moisture carryover is bound to contain chlorides, giving rise to chloride
stress corrosion and subsequent cracking.  

I've participated in model steam discussion groups.  Every now and then a
raging battle takes place: stainless steel versus carbon steel.  Nobody ever
gets their mind changed; they stand their ground.  It's usually the case of
unknowing folks who have sunk big money into building a stainless steel
boiler and when they learn about chloride stress corrosion they refuse to
admit they made a big mistake.  Pride.

Best regards,

Orrin

So many projects.  So little time.

Now I'm going to start a debate.  Hopefully (fingers
crossed) it won't be long before I need to start
installing new plumbing on the Huber.  As per
suggestions here and at Steam School I am planning to
use Sch. 80 steel pipe.  I have had two people
recommend stainless steel to me this summer.  Has
anyone gone with stainless?  Which grade of stainless
should I use?  How much more $$$ for stainless?  Give
me your opinions.
