I will turn into a rock if my AI ask me about the material for this expansion joint [smile] Why is it SA-182? hahahahah

They make me wonder this can be made in forged condition. I'm changing my spec. into SA-240 and re-order now. Thank SnTMan

Thank SnTMan It's strange that I ordered that thick expansion joint in SA-182 F 304 (forged condition), but no supplier complain about that.

Dear engineers, It is the first time I design a thick wall expansion joint follow ASME sec VIII div 1 to get U Stamp for the heat exchanger. I am confusing the material use for calculate and fabricate the expansion joint. Is it SA-240 304 or SA-182 F 304? I'm using SA-182, but the search result...

So for my case, design temp. at 649 C should use 304/316 with C>=0.04% or use H grade. I did the strength calculation for 304L and I can afford the thickness of it. 304L even though the code permits but it doesn't meet the requirement. Is that true? Thank you!

Thanks for your reply. Yes, the 304 has higher allowable stress. But to use at temp. over 550 C it must have C>=0.04% But 304L has limited temp. at 649 C. The temp. from 550 to 649 is in conflict. I don't quite understand that

Hi guys, I'm currently dealing with an ASME VIII-1 - 2021 vessel with a design temperature of 649 C. The material required is stainless steel. So as in ASME II-D - 2021, 304L has max. temp at 649 C while 304 has a G12 note for C>=0.04% for temp. >550 C. That is kind of conflict, don't you think...

Link This pdf is pretty interesting. They claim that 310S material can work continuously at 1035 Celsius.

It is 820 C Flu gas input Tube side. The table is limiting 480 C for stainless steel. It is the lowest temperature limit. It's not even reached the creep temperature of SA240 316. Could you please explain that? Thank you.

I have read through API 530, WRC 541 and calculated the time-dependent allowable stress and minimum thickness due to Rupture Design With Constant Temperature. But they only available to 1500F. I just need to confirm that it can operate in 10 years within the input above. I think I'm going to...

Thanks for your advice, I will draw the curve again following Annex 10.B, try to understand the method. Since I couldn't draw it by hand, the software helped me with this right after I typed the properties of the material in. Dear GD2, This input data is based on the process data of the...

Thank you so much for all the help! TGS4, GD2, EdStainless I am now know exactly where they get those numbers for Y and UTS thank to TGS4. Really appreciate that. So what if I want to calculate for the temperature above 816C, where should I take the input to do FEA? Could you please show me...

Thank you for your reply, TGS4! Sorry for my bad English. My task is to confirm that we can use SS310S and SS316 for this Heat exchanger (HE) to run normally for at least 10 years. I have an old strength report for this condition using elastic-plastic analysis method based on ASME VIII Div. 2...

Dear Engineers, I am running into a problem finding or calculating Yield Stress (MPa) and Ultimate Tensile Stress (MPa) for SUS310S and SUS316 using ASME Section II Part D to match the table as attached. I am running FEA based on ASME Section VIII Div.2 Part 5.3.3 - Elastic-Plastic Analysis...
