PHILSTAIN 347

AWS Specification: AWS A5.4 E347-16

JIS Specification: JIS Z 3221 D347-16

Other Specification: DIN 8556 E19 9 Nb R 23

 

I. APPLICATIONS:

It is used for welding of 18%Cr-8%Ni-Ti (AISI 321) and 18%Cr-8%Ni-Cb (AISI 347) because of its excellent creep-rupture property at high temperature.

II. DESCRIPTION:

PHILSTAIN 347 is composed with 19%C4-9%Ni-Cb and is more stable resistance to intergranular corrosion than NSS-308L with the addition of columbium as carbon stabilizer.

III. NOTES ON USAGE:

• Remove dirts such as oil and dust from the groove.

• Normally, preheat is not necessary.

• Keep the arc length as short as possible.

• Rebake the electrode at 200-250ºC for about one hour before use.
