ENiCrFe-3 electrode is made on a nearly matching core wire with a basic flux system designed to produce optimum operability and demographically sound weld metal. ENiCrFe-3 is optimised for DC+ welding in all positions including pipework qualified in Asme 6G position. Recovery is about 110% with respect to core wire, 65% with respect to whole electrode.These weld metals have no direct equivalent parent material, although the composition is related to Inconel 600. Mn and Nb are added to give a high resistance to hot cracking , tolerance to dilution by many combinations of nickel-base and ferrous alloys, with stable properties over a wide range of service temperatures from -269deg C to above 900deg C.
Applications include heat-resisting nickel-base alloys to themselves for use in furnace equipment up to about 900deg C.Mixed welds between most nickel-base alloys, including Monel 400 and stainless, low alloy or CMn steels without need to preheat.Transition welds between creep resisting ferritic and austenitic steels, such as 2CrMo and 316H for long term service at elevated temperature in petrochemical and power generation plants. Low temperature applications such as 3% or 5% Ni Steels used for cryogenic vessels and pipework in service at or below -100deg C. Stress relief may be carried out if required.
Re-dry at 200-300deg C for 1-2 hours.
