Dear All Experts;

I am trying to make a welding analysis for SA 387 GR 11 material.
and to complete this analysis I need the thermo physical and mechanical values of material SA 387 GR 11. where can I find out these values.

I would appreciate it if someone could give some suggestions

Best regards.

Refer ASME (Boiler and pressure vessel code) BPVC Section II-Materials, Part D-Properties or API/ASME 579: Fitness for service. You will find thermal, mechanical properties with temperature derating (till~500-600deg C).

But welding analysis would require properties till melting temperature/phase transformation change input which you may need to look in research papers or theses.

Dear NRP99

thank you for your reply and suggestion.

I read a lot of paper and articles about welding and residual stresses but I have not seen any paper related SA 387 GR 11 C2.

thermal and mechanical properties in BPVC Section II Part D Properties till 800 C.

thank you again for your reply.
