Max. Allowable stress for Alloy 2205
Max. Allowable stress for Alloy 2205
(OP)
Does anyone have the Max. Allowable Stress values for Alloy 2205 (UNS S31803). I'm trying to calculate the minimum wall thickness for a given pressure and vessel size as per ASME Sec VIII. The temperature range that I'm interested in is 250°F to 550°F. Thank you in advance for any help anyone can provide.

Thank you for your prompt response. Actually, I'm not doing the "design work", but only calculating the minimum allowable thickness to determine the serviceability (and the maximum allowable pressure)of the vessel. Yes, I have used the tables in ASME Sec. II, but two years ago, I was transferred from our Maintenance Engineering Group (made defunct by down-sizing) to a Project Engineering group, and no one has kept the Code books current. I think UNS S31803 may now be listed in the Code book, but I don't think it was in our vintage book.
