The latest CII does not cover B407 N08810, how to address such problem? I am doing the analysis of piping fabricated from B407 N08810 , and operating temp. is 750 cels. degrees.
If the material doesn't appear on ASME B31.3, it is certainly contained in ASME SECTION II PART D: Nonferrous material table, here you can find all characteristic and input that in caesar material database.
