Dear all ,

There are so many kinds of material for us to choose the flange/
bolt material in flange leakage analysis.
We can find the same material description corresponded to several items.
(ex:bolt material A193 B7 has 3 items for us to choose)
My question is how to identify them and what's the definiton of in "class / thickness" which is including in material data-sheet?

Best regards,

ccckkkk,

I suggest that you obtain the Practical Guidbook to ASME II Materials Index by CASTI Publishing. www.cast-publishing.com
