NIHONWELD N-NiCrFe-4

AWS Specification: ENiCrFe-4
JIS Specification:

NONE

Other Specification:

I. APPLICATIONS:

N-NiCrFe-4 is designed for shielded metal arc welding of 9% nickel steel such as ASTM A333, A334, A353, A522, AND A553. However is can also be used for joining Incoloy® 800 to itself or to high nickel alloys 200 and 201. For joining Incoloy® 800 to 9% nickel steels or to nickel-copper Monel® 400 and K-500.

      II. DESCRIPTION:

     N-Ni-CrFe-4 is a nickel-chromium-iron flux-coated electrode very similar to however NIHONWELD N-NiCrFe-4 offers two distinct features that are not available with N-NiCrFe-4 offers a higher yield and tensile strength and it is formulated to operate with AC current, a feature that will allow to combat magnetic arc blow.
