AWS ERNiCrMo-17 / UNS N06200 — Welding wire specifications, parameters, and applications for nickel alloy fabrication.
Hastelloy C-2000 (AWS ERNiCrMo-17) is a nickel-chromium-molybdenum-copper welding wire for welding Hastelloy C-2000 alloy. The copper addition provides enhanced resistance to reducing acids, making it versatile for both oxidizing and reducing environments.

Values above are typical for as-welded Hastelloy C-2000 (ERNiCrMo-17) deposited metal under AWS A5.14 classification requirements. Actual results vary with welding process, heat input and shielding gas.
Follow these practical guidelines to obtain sound, corrosion-resistant welds with this filler metal:
Hastelloy C-2000 (ERNiCrMo-17) is the matching filler for its base alloy and is specified for joints where its particular corrosion or high-temperature performance is required. Match the wire form and diameter to the welding process and section thickness:
The copper addition is what distinguishes C-2000 from other C-series fillers, so specify ERNiCrMo-17 by AWS class and UNS N06200 rather than a generic "Hastelloy C" wire. For duties where only oxidising-acid resistance is needed, see Hastelloy C-22 as an alternative.
ERNiCrMo-17 welds Hastelloy C-2000 to itself and is widely applied as a corrosion-resistant overlay on carbon-steel vessels and piping by GMAW, SAW or electro-slag strip cladding. The copper-bearing chemistry tolerates both oxidising and reducing acids, so a single wire can be stocked for mixed-acid plants rather than two different C-series fillers.
Nickel-alloy filler metals are sensitive to moisture, surface contamination and trace impurities, so proper storage and handling are essential to weld integrity:
Hangbo Alloy Group supplies Hastelloy C-2000 (ERNiCrMo-17) welding wire with full EN 10204 3.1 material certificates, cast/lot traceability and chemical and mechanical test reports. Contact our sales team for batch-specific certification or technical support.
C-2000 adds roughly 1.6% copper, markedly improving resistance to reducing acids such as sulphuric and hydrofluoric acid, while high chromium retains oxidising-acid resistance. See the Hastelloy C-276 vs C-22 comparison for related context.
Yes. It is frequently applied as a corrosion-resistant overlay on carbon steel vessels and piping using GMAW, SAW or electro-slag strip cladding.
Not normally. The ultra-low carbon level allows as-welded service in most chemical process duties.
AWS ERNiCrMo-17 / UNS N06200 with about 22-24% chromium, 15-17% molybdenum and 1.3-1.9% copper, nickel balance and carbon held to 0.01% max. The copper addition is the key for reducing-acid resistance.
AWS A5.14 (ERNiCrMo-17), ISO/EN 18274 (S Ni 6200) and ASME SFA-5.14. Order against the AWS classification and UNS number to remove ambiguity.
TIG wire in 1.6, 2.0, 2.4 and 3.2 mm straight lengths, MIG wire on D200/D300 spools in 0.8-1.6 mm, and SAW coils in 2.4-4.0 mm.
Up to about 1040 °C (1900 °F), with the low carbon content preserving as-welded corrosion resistance.
Pure argon (99.995%) for GTAW; argon with 2% helium or 2% CO2 for GMAW.
Keep interpass temperature below 120 °C, use stringer beads, and back-purge root passes with argon. The 0.01% max carbon also minimizes carbide precipitation.
