Dear friend,
ERCoCr-A can be hard faced as overlay on A217-CA15 type cast material by GTAW process, which is equivalent to A276 410 composition, since A276- 410 is bar material and no code is allowed to hard face or deposit on these type of bar material.
PWHT can be followed as per ASME sec VIII div 1 standard with reference to Pno :6 ,time & temperature also avilable.
regards.

Dear Experts,
Need your opinion for ERCoCr-A hard facing overlay on A276 410 ( with 2.5mm finished overlay thickness) by GTAW Welding Process.
1. What weld parameters required for welding.
2. PWHT requirement (time & temperature required).
Thanks & Regards,
