What is ERNiCrFe-6?
ERNiCrFe-6 is a titanium-bearing nickel-chromium-iron filler wire (N07092, IN-92) developed for welding Alloy 800/800H and similar heat-resistant Ni-Fe-Cr alloys where weld and base-metal thermal expansion need to match. As-welded deposits run about 410 MPa yield, 655 MPa tensile, 35% elongation and 185 HB (90 HRB), with service to roughly 950 °C, and the product is offered only as drawn wire and rod for GTAW and GMAW. The titanium addition makes the pool sluggish and oxide-prone, and availability is narrower than for ERNiCr-3 or ERNiCrFe-5, which are the usual substitutes. ERNiCrFe-6 has a density of 8.2 g/cm³ (0.296 lb/in³), lighter than 63% of nickel alloy grades. It melts at 1,355°C (2,471 °F). ERNiCrFe-6 has a yield strength of 410 MPa (59.5 ksi) and a tensile strength of 655 MPa (95 ksi) — stronger than 60% of nickel alloy grades. Elongation at break is 35% and the elastic modulus is 207 GPa (30 Msi).

Working with ERNiCrFe-6
Is ERNiCrFe-6 easy to machine?
Weld deposits machine like Alloy 600 — gummy and work-hardening; use rigid setups, sharp positive-rake carbide, heavy feed, low SFM and flood coolant.
Can ERNiCrFe-6 be welded?
GTAW or short-arc GMAW with argon (add He for wider penetration); keep interpass below ~150 °C, low heat input, stringer beads and no weaving, and back-purge to avoid Ti/Cr oxide entrapment.
Can ERNiCrFe-6 be formed, bent or molded?
Supplied only as drawn wire/rod; the alloy cold-draws well but requires frequent intermediate annealing due to rapid work hardening.
ERNiCrFe-6 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 ERNiCrFe-6?
Do not anodize; remove Ti-rich oxide by stainless brushing or pickling before subsequent passes, then passivate or leave bright — accepts electropolishing and nickel/chrome plating.

ERNiCrFe-6 — frequently asked
What is ERNiCrFe-6 used for?
ERNiCrFe-6 is typically used for incoloy 800H furnace tubing, petrochemical reformer components and heat-resistant fabrication. In short: expansion-matched to Alloy 800H; heat-resistant Ni-Fe-Cr filler; wire and rod only.
What is the yield strength of ERNiCrFe-6?
ERNiCrFe-6 has a typical yield strength of 410 MPa (59.5 ksi) and a tensile strength of 655 MPa (95 ksi) — stronger than 60% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ERNiCrFe-6 easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Weld deposits machine like Alloy 600 — gummy and work-hardening; use rigid setups, sharp positive-rake carbide, heavy feed, low SFM and flood coolant.
Can ERNiCrFe-6 be welded?

What is the maximum service temperature of ERNiCrFe-6?
ERNiCrFe-6 is rated for continuous use to about 950°C (1,742 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCrFe-6-AW and ERNiCrFe-6 AW-PWHT?
AW is the default condition — default condition for any filler metal: properties of the as-deposited, undiluted weld metal used for procedure qualification. AW-PWHT: choose when the joint must be stress-relieved or matched to a solution-annealed Alloy 600/800H base metal; slightly lowers strength and raises ductility. Yield strength is 410 MPa in AW versus 320 MPa in AW-PWHT.
How much does ERNiCrFe-6 cost?
