Dear Experts,
Good Day!
I have welded(GTAW) a PQR of 17-4PH stainless steel with ER630(Client requirement) as per ASME Sec IX.
In bend test, my specimen is cracking at center of weld. Sample thickness is 16mm and side bend radius was chosen as 67mm as per BM elongation percentage 13% min as per material code.
But ER630 is having minimum elongation of 7% as per Sec II-C and my consumable was not bend tested at manufacturer end.
Please guide me through this.
Regards,
M.Raghuvamshi
