Dear all
With regard to Mr. P.Rao question :
1- Use EB2 materials group.
2- 690 ±14 °C is better range for PWHT.
3- Pay attention to 149 °C preheat and a suitable post heating.
4- Check edges and bevels for hardness before welding.
5- Check PWHT plus any intermediate treatment ( above 482°C) on LMP.

Subject: [MW:3835] SA387 Gr.11 Cl.2 material welding.
Dear all,
Can any body have experiance on welding of SA387 Gr.11 Cl.2 (1 1/4Cr-1/5 Mo)material with E8018-B3L, ER80S-B3L, EB3 type welding consumables(2 1/4 Cr-1Mo).
Higher composition consumables (B3L) are recommended?
Is there any change in PWHT is required as compared to standard PWHT cycle for SA387 Gr.11 Cl.2 material as per ASME Div.1.
Pl. share experiance on welding of subject material.
( Design Code : ASME div.1
MDMT : 0 Deg.C
Impact : 50/40)
regards
P.Rao
