Values for the AW condition
ERNiCr-3 tempers and conditions
ERNiCr-3 is supplied in 4 conditions, soft to hard. AW is the default FabDigit quotes; the values on this page are for it.
Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Solution annealed weld metal / annealed cut-length rod | Condition of straight-length GTAW rod as supplied and of weld metal given a full solution anneal (~1010–1100 °C) — softest, most ductile state. | 320 | 590 | 45 | 160 HB | 1.6 % IACS |
As Welded + PWHT | Pick when the joint must follow the base-metal PWHT cycle (e.g. Alloy 600 to low-alloy steel); slight strength drop, ductility retained. | 370 | 600 | 40 | 170 HB | 1.6 % IACS |
AWDefault As-welded deposit | Default reported condition: undiluted all-weld-metal properties per AWS A5.14 qualification, used for design of as-welded joints and overlays. | 400 | 620 | 38 | 180 HB | 1.6 % IACS |
Cold drawn spooled wire (MIG/MAG, hard temper) | As-drawn/temper-drawn layer-wound wire for GMAW and mechanized welding; the higher wire strength is for feedability/column strength, not for joint design. | 700 | 830 | 20 | 24 HRC | 1.5 % IACS |

What is ERNiCr-3?
ERNiCr-3 is a bare Ni-Cr-Fe-Nb filler wire (Alloy 82, UNS N06082) classified to AWS A5.14, used for GTAW, GMAW, PAW and SAW of Alloy 600/690 and dissimilar metal joints, often as the root pass under ENiCrFe-3 covered electrode fill. As-welded deposits show about 400 MPa yield, 620 MPa tensile, 38% elongation and 180 HB (88 HRB), with service to 815 °C. Machinability is low at 24/100 and the deposit work-hardens quickly; the product is supplied as cold-drawn spooled wire and cut lengths. Choose ERNiCrMo-3 (625) where Mo-bearing corrosion resistance is needed. ERNiCr-3 has a density of 8.3 g/cm³ (0.3 lb/in³), lighter than 52% of nickel alloy grades. It melts at 1,354°C (2,469 °F). ERNiCr-3 has a yield strength of 400 MPa (58 ksi) and a tensile strength of 620 MPa (89.9 ksi) — stronger than 56% of nickel alloy grades. Elongation at break is 38% and the elastic modulus is 200 GPa (29 Msi).

Working with ERNiCr-3
Is ERNiCr-3 easy to machine?
Weld deposits work-harden fast and are gummy: use rigid setups, positive-rake carbide, low speed / heavy feed and flood coolant; grinding of overlays needs soft aluminum-oxide wheels.
Can ERNiCr-3 be welded?
Designed as filler: GTAW/GMAW/PAW/SAW with Ar or Ar-He shielding, stringer beads, interpass ≤150 °C, no preheat needed on nickel base metals; keep dilution from carbon steel low to avoid Fe pickup.
Can ERNiCr-3 be formed, bent or molded?
Supplied as drawn wire — cold drawing and coiling only; re-straightened rod bends easily in the annealed state but work-hardens rapidly.
ERNiCr-3 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on ERNiCr-3?
Remove all oxide/heat tint by pickling, stainless wire brushing or grinding before further passes or service; electropolish or passivate for nuclear/clean-service cleanliness; not anodizable.

ERNiCr-3 — frequently asked
What is ERNiCr-3 used for?
ERNiCr-3 is typically used for nuclear dissimilar metal welding, alloy 600/690 pipe welding and root pass welding before covered electrode fill. In short: bare-wire partner to 182; service to 815 °C; standard nuclear root filler.
What is the yield strength of ERNiCr-3?
ERNiCr-3 has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 620 MPa (89.9 ksi) — stronger than 56% of nickel alloy grades. Strength varies by condition: see the 4 listed tempers.
Is ERNiCr-3 easy to machine?
Not especially — machinability is rated poor (24/100, better than 71% of nickel alloy grades). Weld deposits work-harden fast and are gummy: use rigid setups, positive-rake carbide, low speed / heavy feed and flood coolant; grinding of overlays needs soft aluminum-oxide wheels.
Can ERNiCr-3 be welded?
Yes — weldability is rated excellent (92/100). Designed as filler: GTAW/GMAW/PAW/SAW with Ar or Ar-He shielding, stringer beads, interpass ≤150 °C, no preheat needed on nickel base metals; keep dilution from carbon steel low to avoid Fe pickup.
What surface finishes work on ERNiCr-3?
Remove all oxide/heat tint by pickling, stainless wire brushing or grinding before further passes or service; electropolish or passivate for nuclear/clean-service cleanliness; not anodizable.
Can ERNiCr-3 be formed, bent or molded?
Supplied as drawn wire — cold drawing and coiling only; re-straightened rod bends easily in the annealed state but work-hardens rapidly.
What is the maximum service temperature of ERNiCr-3?
ERNiCr-3 is rated for continuous use to about 815°C (1,499 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCr-3-AW and ERNiCr-3 SOL-ANN?
AW is the default condition — default reported condition: undiluted all-weld-metal properties per AWS A5.14 qualification, used for design of as-welded joints and overlays. SOL-ANN: condition of straight-length GTAW rod as supplied and of weld metal given a full solution anneal (~1010–1100 °C) — softest, most ductile state. Yield strength is 400 MPa in AW versus 320 MPa in SOL-ANN.
How much does ERNiCr-3 cost?
ERNiCr-3 is a high-cost nickel alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
