SA-737 Moduli of Elasticity

Hello everybody.
I have steel SA-737 Gr.B
Nominal composition is C-Mn-Si-Cb. Well, I use table TM-1 from ASME BPVC Section II part d to know Moduli of Elasticity to use it in calculations.
What string shall I use? Material group A?
Thanks for advance!

RE: SA-737 Moduli of Elasticity

Yes, this would be the closest material grouping.

Great!
But in Table 3-D.2M from ASME BPVC div.2 Section VIII it will be carbon steel the nearest group to determinate Ncss and Kcss? Yes?
Thank you for help!

RE: SA-737 Moduli of Elasticity

The SA 732 material specification is low alloy because of the small addition of columbium, which results in a fine grained texture and increased strength to some extent. Overall, it is closest a microalloy carbon steel.
