[pradip kumar Sil]

Dear All,

We have to weld A-240 TP 409 to A-240 TP 409 ( P-7 to P-7  Material ) & which Filler we can use ER 309L /ERNiCr-3.

Temperature is around 300 degree centigrade ( HRSG Bottom area this material is coming ) where this wps will be used.

Thanks in advance

Regards

You can use ER309/309L

[S.Mohammed]

Er nicr3 to be used for high temp

[LALU RAJENDRAN]

for temp around 300 deg, we normally use austenitic filler wire such as ER 309L. But for HRSG bottom area, the temperature would be higher and you may uses  ERNiCr-3.

regards,

LALU

Hi,

ER 430 is correct consumable, but you need PWHT.

With out PWHT I have qualified with E NiCrMO3.
E 309L will not pass in bend test.
