YES, Weld of ER90S-B3+E9018-B3 temperature around 720-730°C (1330-1345°F), for 2 hours, this temp is
sufficient to temper the P91 HAZ without over-tempering the P22,

Thanks Mr. Rajesh,I have gone through the chemical composition of ER90S-B3, but it is likely to match 2 1/2 Cr. alloy steels. Will it be compatible for 9 Cr. steel?RegardsVadivel. M

use GTAW : ER90S-B3 , PWHT 720-730 , 2 hrs or
GTAW +SMAW : ER90S-B3+E9018-B3 , PWHT 720-730 , 2 hrs or
GTAW +FCAW : ER90S-B3+E91T1-B3 , PWHT 720-730 , 2 hrs

Would be better combination of GTAW and SMAW.
What is your thickness?
What is your construction Code / Standard?best regards

Dear Experts,
I need to weld P15E(C12A/P91 - High alloy steel) material with P5A(WC9/P22 - Low alloy steel).
Can you please guide me on MIG Filler wire that needs to used for this combination.
Thanks and regards
Vadivel. M
