What is ERNiCr-3-AW?
ERNiCr-3-AW is ERNiCr-3 heat treated to AW — default reported condition: undiluted all-weld-metal properties per AWS A5.14 qualification, used for design of as-welded joints and overlays.

Elongation at break is 38% and the elastic modulus is 200 GPa (29 Msi). ERNiCr-3-AW 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).
Advantages
- Readily welded — 92/100, better than 98% of nickel alloy grades
- Tough — resists crack growth — 120 MPa·√m (109.2 ksi·√in), better than 75% of nickel alloy grades

Working with ERNiCr-3-AW
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.
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-AW — frequently asked
What is ERNiCr-3-AW used for?
ERNiCr-3-AW 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-AW?
ERNiCr-3-AW 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-AW 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-AW 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-AW?
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-AW 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-AW?
ERNiCr-3-AW 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.
