316/316L
(OP)
Hi all,
I'm designing a pressure vessel using some 10in NPS pipe, and I would like to know if I can use this kind of material. We have pipe we would like to use that is certified 316/316L. When we checked the boiler and pressure vessel code it lists pressure and temperature ratings for 316 stainless up to 1500 degF but the 316L rating doesn't go as high. I would like to know if anyone can tell me, preferably with a link to the source, what the pressure temperature ratings for 316/316L are. Moreover, I need to make sure that they are as high as (or close to) what the code lists for 316.
Thank you for the help,
Bruno

RE: 316/316L
In cases like this, you are permitted to use the properties listed for either of the two materials: 316 or 316L.
There is a code interpretation on this somewhere I'm sure but I don't have the reference right now but if you wanted to scan through them, you should be able to find it.

the pipe and fittings meet both specifications
if you are required to use 316 use the 316 charts
if you are required to use 316L use the 316L charts

Pull out Section II-D 2009 and flip it open to page 892.
The rest goes on to answer your question in more detail. You might have to pay attention to carbon content in the MTR. Enjoy!

Question: Stainless steel materials have been received from suppliers with dual markings and dual certifications for 304/304L and 316/316L. Material test reports show that the material meets all the chemical and physical requirements of Section II, Part A for the specific material. May this material be used in the design and construction of both plain grade and low-carbon grade stainless steel vessels?
Reply: Yes.

What section is your vessel built? For what service?

I regularly design 316L vessels using the higher allowables of 316 as long as I am sure the material will be dual certified.
