What is ERNiCrMo-2?
ERNiCrMo-2 is a nickel-chromium-iron-molybdenum filler wire (UNS N06002, AWS A5.14 family) matching Hastelloy X, used where welds must keep oxidation resistance and strength at very high temperature. It is chosen for aerospace and gas turbine hot-section fabrication and is supplied as cold-drawn spool wire; as-welded deposits run about 430 MPa yield, 730 MPa tensile, 36 % elongation and 200 HB (92 HRB), with service to 1150 °C. It is a high-temperature filler, not an acid-service filler, and machinability is low (score 25); for wet chloride or acid corrosion use ERNiCrMo-4. ERNiCrMo-2 has a density of 8.22 g/cm³ (0.297 lb/in³), lighter than 60% of nickel alloy grades. It melts at 1,260°C (2,300 °F). ERNiCrMo-2 has a yield strength of 430 MPa (62.4 ksi) and a tensile strength of 730 MPa (106 ksi) — stronger than 64% of nickel alloy grades. Elongation at break is 36% and the elastic modulus is 205 GPa (29.7 Msi).

Working with ERNiCrMo-2
Is ERNiCrMo-2 easy to machine?
Weld deposits and the alloy generally machine like a tough austenitic superalloy: rigid setups, positive-rake carbide or ceramic tooling, low surface speed, heavy flood coolant and no dwelling to avoid work hardening.
Can ERNiCrMo-2 be welded?
GTAW/GMAW/PAW and laser hot-wire on Hastelloy X, 617, 625 and dissimilar Ni/stainless joints; keep interpass temperature low, use stringer beads and low heat input, argon or Ar-He shielding with full back purge to avoid microfissuring.
Can ERNiCrMo-2 be formed, bent or molded?
Supplied as cold-drawn wire; the deposited metal is highly ductile in solution-annealed condition but work-hardens quickly, so plan intermediate anneals for any cold forming of welded assemblies.

What surface finishes work on ERNiCrMo-2?
Pickle or blast to remove chromium-rich weld oxide before service or coating; not anodisable, but takes electropolishing, aluminide/diffusion coatings and thermal-barrier bond coats well.

ERNiCrMo-2 — frequently asked
What is ERNiCrMo-2 used for?
ERNiCrMo-2 is typically used for gas turbine combustor liners, aerospace furnace fixtures and high-temperature sheet metal fabrication. In short: matches Hastelloy X; rated to 1150 °C; oxidation-resistant weld metal.
What is the yield strength of ERNiCrMo-2?
ERNiCrMo-2 has a typical yield strength of 430 MPa (62.4 ksi) and a tensile strength of 730 MPa (106 ksi) — stronger than 64% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is ERNiCrMo-2 easy to machine?
Not especially — machinability is rated poor (25/100, better than 76% of nickel alloy grades). Weld deposits and the alloy generally machine like a tough austenitic superalloy: rigid setups, positive-rake carbide or ceramic tooling, low surface speed, heavy flood coolant and no dwelling to avoid work hardening.
Can ERNiCrMo-2 be welded?
Yes — weldability is rated excellent (88/100). GTAW/GMAW/PAW and laser hot-wire on Hastelloy X, 617, 625 and dissimilar Ni/stainless joints; keep interpass temperature low, use stringer beads and low heat input, argon or Ar-He shielding with full back purge to avoid microfissuring.
What surface finishes work on ERNiCrMo-2?

Can ERNiCrMo-2 be formed, bent or molded?
Supplied as cold-drawn wire; the deposited metal is highly ductile in solution-annealed condition but work-hardens quickly, so plan intermediate anneals for any cold forming of welded assemblies.
What is the maximum service temperature of ERNiCrMo-2?
ERNiCrMo-2 is rated for continuous use to about 1,150°C (2,102 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCrMo-2-AW and ERNiCrMo-2 AW-SA?
AW is the default condition — default condition for qualification and most aerospace/turbine joints where no post-weld heat treatment is applied. AW-SA: best choice for maximum ductility and homogeneous, carbide-free weld structure before long-term high-temperature service or subsequent forming. Yield strength is 430 MPa in AW versus 360 MPa in AW-SA.
