Selection of Filler/Electrode.

[HerculanJohn]

Dear Gentlemen,

Kindly advise me as we have tube to tubesheet joint.

Tube moc is incoloy 800

And tubesheet moc is F53 SDSS (Super duplex stainless steel).

For incoloy-800 -- P NO : 45

For F53 SDSS-- P NO: 10H

Which filler wire is applicable please suggest.

Best Regards,

John

For best results, use AWS A 5.14 ER Ni Cr-3 (Incoloy 800) filler wire for the weld metal when joining the Incoloy 800 tube to Super Duplex 

F53 SDSS tube sheet. This filler wire provides good compatibility with both materials, accommodates differences in thermal stability, and 

maintains corrosion resistance and mechanical strength. 

Alternatively, AWS A 5.14 ERNiCrMo-3 (Inconel 625) could be used for a Chloride rich or acidic atmosphere.

rgds,

C Sridhar.

i think that NICr3 is Inconel 600.

Inconel & Incoloy have vast differences in % Fe. content.
