A395 Sm value
A395 Sm value
(OP)
I've been through Section II, Part D, Table 2A several times and can't find Sm list for A395. Other cast material is listed in this section but not A395. Have I missed it or am I missing something about this material and how Sm is applied to it?

SA-395 is not listed in Table 2A.
What particular ASME code are you intending to use SA-395?

Thanks for the info.
Is there any reference you can give for this or just based on your experience?
RE: A395 Sm value
My statement above regarding the value of Sm is based on the maximum stress theory used by ASME B&PV code.
Yielding can be determined by two current approaches;
the maximum shear stress (Tresca) or the maximum distortion energy (vonMises).
The simplest is the maximum shear stress theory where yielding occurs when the maximum shear stress value reaches 1/2 the tensile yield stregnth.
