Which is correct in B31.1 -2010:
(1) Table 104.1.2(A) Values of Y, general note (a) which states: "For cast iron and non-ferrous materials, Y = 0."
or
(2) Table A-_ (material tables) general notes which have Y = 0.4 (except for some nickel alloys)
I realize Y = 0 is most conservative...
I have questions pertaining to the metal groups noted in ASME B31.3, Table 304.1.1 Values of Coefficient Y?:
Ferritic steels: Are they only the 400 series SS, duplex, and super duplex austenitic-ferritic SS?
Austenitic stainless steels: Are they 300 series SS and super SS (904L SS)...
Hi, B31.1 was changed in the 2005 version to show coefficient y=0 for cast iron and non-ferrous materials. The previous version had y=0.4.
Will B31.3 have a similar change?
B31.3 shows only cast iron having y=0. I assume the non-ferrous materials fall in the "other ductile metals" category.
