Home Products Nickel based Electrodes RATNA B Ni 70 (AWS A5.11 ENiCrFe 3)

Nickel-base Alloy Basic Coated Electrode for Yielding Weld Deposition

Classification:

  • AWS/SFA-5.11: E NiCrFe-3

Characteristics:

A basic coated Ni alloy electrode producing Inconel weld deposit. Electrode exhibits excellent results while welding 5% & 9% Ni steels, Inconel steels under low temperature applications. Produces crack-free joints which are highly resistant to oxidation and corrosion.

Applications:

  • Suitable for Nickel and Nickel-based alloys.
  • Base materials: Inconel 600, Nimonic 75, Monel 400.
  • Can be welded to mild steel, low alloy steel, and stainless steels.
  • Low temperature applications such as 5% & 9% Ni steels used for Cryogenic vessels & pipe work for temperatures down to -100°C.
  • Elevated temperature services in furnace equipment & petrochemical plants.
  • Joining and surfacing in critical fabrications.

Re-Dry Condition:

Re-dry the electrode at 250°C for 1 hour before use.
