Stainless Steel Properties at Elevated Temperatures

[NAUGDOGG]

Hello all,

My work involves some stress analyses at high temperatures. I typically work with stainless steel weldments, but I am having trouble finding reliable yield strength values at these extreme temperatures (up to 1800°F) for evaluation of the designs. Can anyone suggest a code or other reliable source where I can determine allowable stresses for stainless steels at elevated temperatures?

Thank you for your help.

ASME Boiler and Pressure Vessel Code, Section II, Part D, Table 1A. You also need to review and understand the rationale for assignment of allowable stresses in Section II.

What alloys? It may be in the ASM High Temperature Property Data: Ferrous Alloys.

Some of the typically used mateirals are: 304, 304L, 309, 316 & 410.
I'm looking into the BPVC, Section II, Part D. However, those codes do not come cheap. For just Part D of Section II of the code it costs $690!!

From the fore mentioned book: (temp in F, strength in ksi, UTS/yld)
304 RT 97/59 1600F 17/16 1800F 10/9
304L no data, it will be weaker
309 RT 90/42 1600F 21/18 1800F 11/na
310 RT 91/42 1600F 27/16 1800F 13/na
316 data only goes to 1600F 24/16
410 strength will depend greatly on C content
high C 1600F 14/9
low C 1600F 11/7

Understand the cost issue completely. This is why elevated temperature tensile data needs to be evaluated for use with assigned knockdown factors.

To echo, at this temp you are creep limited, not strength limited. This become critical because even at zero applied load you will get distortion of these materials at 1800F.
This take careful design work to avoid unpleasant and very expensive results.

Hello everybody,

There are some useful data in Boller-Seeger and Baumel-Seeger series of books "Materials data for cyclic loading".

As a part of my academic effort (I work on methods for estimation of cyclic and fatigue material properties) I have put together database of referenced material datasets.
Authors allowed me to include data from these books in it.
I don't want this to be considered advertising, so contact me directly, if you need access to these data.

Best regards,

Assist. Prof. Basan Robert, D. Sc.
