409 stainless steel piping
409 stainless steel piping
(OP)
Hi,
I've tried to find 409 stainless steel piping for the last week. All I find is 409 tubing as per ASTM A268. But this kind of tubing is too thin for my needs. I need a 8" sch 80 409 stainless steel pipe.
I'm thinking about casting it now, does anybody knows where can I find such piping.

RE: 409 stainless steel piping
The mechanical properties fall off with increasing thickness. This is because it has to be cold reduced over 60% to get enough driving force for the full recrystallization which gives it a fine enough grain size not to be very lacking in toughness, hence not a favorite for much heavier in gage than exhaust pipe.

so I conclude that I won't find it anywhere. What I'll probably do is cast it.
I really don't need strong mechanical properties for this application, it is just a corrosion allowance to protect from a mixture of air-HCl-chlorine gas at 500 C. It is not welded, it is supported by bracket and it act as a deflector.
thanx again

P.S. Hey, and the alloy can't have any nickel (less than 0.5%) ...

Why don't you buy some sheet 409 and have it fabricated. Or get 410 which can be used in heavier gauges without these problems.
