NT-NiCrFe-5 / NM-NiCrFe-5
AWS Specification: AWS A5.14 ER NiCrFe-5
JIS Specification:

Equivalent to INCONEL FM62

Other Specification:

FOR NICKEL ALLOYS

I. APPLICATIONS:

For high temperature strength, oxidation resistance.

II. DESCRIPTION:

 

The higher niobium content of NT-NiCrFe-5 is intended to minimize

cracking where high welding stresses are encountered, as in thick-

section base metal up to 2”.
