Working with ERNiCrFe-5-AW
Is ERNiCrFe-5 easy to machine?
Weld deposits machine like alloy 600 — low speed, heavy positive-rake sharp carbide tools, rigid setup and flood coolant to avoid work hardening; grind flush rather than mill where possible.
Can ERNiCrFe-5 be welded?
Runs on GTAW/GMAW/SAW with Ar or Ar-He shielding; keep interpass below ~150 °C, use stringer beads and low heat input, and clean between passes to avoid oxide entrapment in the sluggish pool.
Can ERNiCrFe-5 be formed, bent or molded?
Supplied as cold-drawn wire; the deposit is highly ductile and can be cold worked or bent after welding, but springback and work hardening are high.
What surface finishes work on ERNiCrFe-5?
Pickle or abrasive-blast plus passivation to remove chromium heat tint before service; no anodizing — electropolish or mechanical polish for hygienic/high-temperature cleanliness.

ERNiCrFe-5-AW — frequently asked
What is ERNiCrFe-5-AW used for?
ERNiCrFe-5-AW is typically used for inconel 600 pressure equipment, incoloy 800H components and petrochemical furnace tubing repairs. In short: stronger than ERNiCr-3; nb-stabilized Alloy 600 filler; multi-process wire (GTAW/GMAW/SAW).
What is the yield strength of ERNiCrFe-5-AW?
ERNiCrFe-5-AW has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 655 MPa (95 ksi) — stronger than 56% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ERNiCrFe-5-AW easy to machine?
Not especially — machinability is rated poor (22/100, better than 64% of nickel alloy grades). Weld deposits machine like alloy 600 — low speed, heavy positive-rake sharp carbide tools, rigid setup and flood coolant to avoid work hardening; grind flush rather than mill where possible.
Can ERNiCrFe-5-AW be welded?
Yes — weldability is rated excellent (92/100). Runs on GTAW/GMAW/SAW with Ar or Ar-He shielding; keep interpass below ~150 °C, use stringer beads and low heat input, and clean between passes to avoid oxide entrapment in the sluggish pool.
What surface finishes work on ERNiCrFe-5-AW?
Pickle or abrasive-blast plus passivation to remove chromium heat tint before service; no anodizing — electropolish or mechanical polish for hygienic/high-temperature cleanliness.
Can ERNiCrFe-5-AW be formed, bent or molded?
Supplied as cold-drawn wire; the deposit is highly ductile and can be cold worked or bent after welding, but springback and work hardening are high.
What is the maximum service temperature of ERNiCrFe-5-AW?
ERNiCrFe-5-AW is rated for continuous use to about 980°C (1,796 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCrFe-5-AW and ERNiCrFe-5 PWHT-SR?
AW is the default condition — default condition: properties of the undiluted deposit in the as-welded state, as qualified per AWS A5.14. PWHT-SR: choose when the fabrication is stress-relieved or when the weld follows the base metal's solution/anneal cycle; strength drops slightly, ductility rises. Yield strength is 400 MPa in AW versus 340 MPa in PWHT-SR.
