What is ERNiCrMo-10?
ERNiCrMo-10 is a highly alloyed nickel-chromium-molybdenum-tungsten filler metal (UNS N06022, AWS A5.14 family) that matches Hastelloy C-22 base metal and resists both oxidizing and reducing acids in the as-welded joint. Engineers specify it when a weld must match C-22 plate and pipe for corrosion performance; it is supplied as cold-drawn spool wire and annealed cut rod, with as-welded deposits near 500 MPa yield, 760 MPa tensile, 42 % elongation and 92 HRB. Deposits machine poorly (machinability 18) and wire cost is high; where only chloride pitting and reducing acids are involved, ERNiCrMo-4 (C-276) is the nearest alternative. ERNiCrMo-10 has a density of 8.69 g/cm³ (0.314 lb/in³), heavier than 72% of nickel alloy grades. It melts at 1,357°C (2,475 °F). ERNiCrMo-10 has a yield strength of 500 MPa (72.5 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 73% of nickel alloy grades. Elongation at break is 42% and the elastic modulus is 206 GPa (29.9 Msi).

Working with ERNiCrMo-10
Is ERNiCrMo-10 easy to machine?
Weld deposit machines like solution-annealed C-22: low speed, heavy positive rake carbide, rigid setup and flood coolant; it work-hardens instantly if the tool rubs.
Can ERNiCrMo-10 be welded?
GTAW/GMAW/PAW with 100 % Ar (or Ar+He for GTAW, Ar+He+small CO₂-free mix for pulsed GMAW); stringer beads, low heat input (<1.5 kJ/mm), interpass <150 °C, no preheat, no PWHT required.
Can ERNiCrMo-10 be formed, bent or molded?
Supplied only as drawn wire/rod; annealed rods bend freely for feeding, cold-drawn spool wire is stiffer — keep drive-roll pressure low to avoid shaving.
ERNiCrMo-10 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 ERNiCrMo-10?
Do not anodize; grind/pickle (HNO₃-HF) or electropolish the weld and remove all heat tint to restore full pitting and crevice resistance.
Surface treatments FabDigit runs on nickel alloy parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).
