GETIG 70S-A1

Solid wire alloyed with Molybdenum for improved properties
IDENTIFICATION : ER 70S-A1
CLASSIFICATION : AWS A-5.28 : ER 70S-A1

DESCRIPTION:

Getig 70S-A1 copper coated filler wire for welding 0.5% Mo steels used for creep resisting service at temperatures up to about 500°C.
This wire is copper coated to suppress corrosion but possible deterioration is minimized by storage at <60%RH and>18°C.

Materials to be welded :

  • ASTM A 335 Gr.P1
  • ASTM A 336 Gr.F1
  • ASTM A 185 Gr.F1
  • ASTM A 204 A,B,C
  • ASTM A 209 Gr.T1
  • ASTM A 487 2B (cast)
  • ASTM A 533 CI.3
