HAYNES 230-W Welding Wire (ERNiCrWMo-1) Supplier in Mumbai, India
Nicorex Alloys is an ISO 9001 and ISO 14001 certified supplier, importer, and stockist of HAYNES 230-W welding wire in Mumbai, India. We import and stock ERNiCrWMo-1 filler metal in compliance with the AWS A5.14 ERNiCrWMo-1 (UNS N06231), ASME SFA-5.14, AMS 5839, and EN ISO 18274 S Ni 6231 standards.
HAYNES 230-W filler wire is a Ni-Cr-W-Mo (nickel-chromium-tungsten-molybdeum) wire that consists of approximately 57% Ni, 22% Cr, 14% W, 2% Mo, and 0.03% La. It provides the highest combination of oxidation resistance, thermal stability, and nitriding resistance. Haynes 230-W welding wire welds HAYNES 230 (UNS N06230), Alloy 617 (UNS N06617), and thick-section cobalt alloys such as HAYNES 188. It is grouped as F-43 as per ASME IX QW-432. At Nicorex Alloys, the available forms of these welding wires are TIG rods (0.76–4.70 mm), MIG spools (0.76–2.40 mm), reels, and coils with RTW™ surface finish.
The key industries these ERNiCrWMo-1 welding wires are used in include aerospace gas turbines, land-based power generation, chemical processing, industrial heating, and advanced nuclear concepts. Every shipment of Haynes 230-W welding wire from Nicorex Alloys comes with MTC 3.1 as per EN 10204 certifying conformance to AMS 5839.

Chemical Composition of HAYNES 230-W Weld Deposit (%)
The chemical composition of Haynes 230-W welding wire and itskey alloying elements are listed in the table below:
| Element | Nickel (Ni) | Chromium (Cr) | Tungsten (W) | Cobalt (Co) | Iron (Fe) | Molybdenum (Mo) | Manganese (Mn) | Silicon (Si) | Aluminium (Al) | Copper (Cu) | Carbon (C) | Lanthanum (La) | Phosphorus (P) | Sulphur (S) | Boron (B) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Range (wt%) | Remainder (~57%) | 20.0–24.0 | 13.0–15.0 | 5.0 max | 3.0 max | 1.00–3.00 | 0.30–1.00 | 0.25–0.75 | 0.20–0.50 | 0.50 max | 0.05–0.15 | 0.050 max | 0.03 max | 0.015 max | 0.003 max |
Tungsten (13–15%) is the primary solid-solution strengthener and the reason HAYNES 230 outperforms HASTELLOY X above 871°C (1600°F). Lanthanum (≤0.050%) improves oxide scale adhesion during thermal cycling through La₂O₃ pegs that anchor the chromia scale. Carbon (0.05–0.15%) forms stable M₆C and M₂₃C₆ carbides that resist grain coarsening. Silicon (0.25–0.75%) is controlled for oxidation resistance without promoting hot cracking. Mo at 1–3% is a minor addition: high-temperature strength comes from tungsten, not molybdenum.
All-Weld-Metal Mechanical Properties of HAYNES 230-W
Minimum and typical values for all-weld-metal deposits from ERNiCrWMo-1 in the as-welded or solution-annealed condition are listed below.
| Property | Tensile Strength | Yield Strength (0.2%) | Elongation |
|---|---|---|---|
| Minimum (per AWS/AMS) | 110,000 psi (760 MPa) | — | — |
| Typical | ~120,000–130,000 psi (825–895 MPa) | ~55,000–65,000 psi (380–450 MPa) | ~35–45% |
HAYNES 230 is FCC austenitic with no ductile-to-brittle transition temperature (DBTT). Unlike precipitation-hardened alloys (Inconel 718, HAYNES 282), 230-W is solid-solution-strengthened. Room-temperature strength is moderate, but the advantage emerges above 760°C, where it retains strength for much longer than competing fillers. After 16,000 hours at 649–870°C (1200–1600°F), the base metal retains tensile strength above 130 ksi and impact values above 28 ft-lb, with no sigma, mu, or Laves phase formation.

Recommended Welding Parameters for HAYNES 230-W Filler Wire
The following table provides information about welding parameters for ERNiCrWMo-1 filler wire:
| Process | Polarity | Shielding Gas | Transfer Mode | Notes |
|---|---|---|---|---|
| GTAW (TIG) | DCEN | 100% Argon (pre-purge, trailing, back purge) | Stringer / narrow weave | Back purge required for all root passes. Interpass ≤93°C (200°F); auxiliary cooling permitted if contaminant-free. |
| GMAW (MIG) | DCEP | Argon or Argon-Helium | Short-arc or Spray-arc | RTW™ surface finish on spooled wire promotes smooth feeding and reduced tip wear. |
| SMAW (Stick) | — | — | — | AWS A5.11 ENiCrWMo-1 (UNS W86231). Dry electrodes at the manufacturer-recommended temperature if exposed to moisture. |
Preheat is not required, and PWHT is not generally required. Solution anneal at 1177–1246°C (2150–2275°F) if needed with rapid cool or water quench. Clean welding surfaces with acetone or IPA before welding. Remove all greases, oils, cutting fluids, crayon marks, scale, and dye penetrant residues. The base metal should preferably be solution-annealed when welded.

Industries and Applications of HAYNES 230-W Filler Metal
Nicorex Alloys exports HAYNES 230-W welding wire to fabricators across five sectors where high-temperature oxidation resistance and thermal stability are critical.
- Combustion cans, transition ducts, flame holders, afterburner components, and exhaust assemblies.
- Combustor liners, transition pieces, cross-fire tubes, and recuperator components.
- Catalyst grid supports in ammonia burners (premier nitriding resistance), nitric acid plant internals, high-temperature heat exchangers, and thermocouple tubes.
- Radiant tubes, muffles, retorts, nitriding furnace inserts, heat treatment baskets, burner components, and recuperator inserts.
- Structural components in high-temperature gas-cooled reactors (HTGR), Gen IV molten salt reactor concepts, and high-temperature helium loop assemblies. The combination of nitriding, oxidation, and thermal stability performance makes 230 preferred for next-generation nuclear systems.
Storage and Handling of HAYNES 230-W Welding Wire
ERNiCrWMo-1 is a bare (uncoated) nickel alloy filler metal and does not require re-baking before use. HAYNES 230-W coated electrodes (AWS A5.11 ENiCrWMo-1) do require drying if exposed to moisture.
Store TIG rods in original sealed tubes and MIG spools in sealed packaging in a clean, dry area (15–25°C, <60% RH). Keep wire away from carbon steel storage and grinding stations: airborne iron particles cause hot cracking in nickel alloy weld deposits. Handle with clean, lint-free gloves at all times.
Five contaminants to guard against: sulphur (cutting fluids, fingerprints), lead (paints, anti-seize), zinc (galvanised steel, brass tooling), copper (backing bars, brass fittings), and low-melting-point metals (tin, bismuth, antimony). Use dedicated stainless steel or nickel alloy tools only. Clean base metal to bare metal for at least 25 mm (1 in) on each side of the joint using acetone or IPA, then mechanically clean with a stainless steel brush or carbide burr.

Frequently Asked Questions
What is the Difference between HAYNES 230-W and HASTELLOY X (ERNiCrMo-2) Welding Wire?
Both are nickel-base, solid-solution-strengthened, F-43 fillers under AWS A5.14. HAYNES 230-W contains 13–15% tungsten versus 0.6% in HASTELLOY X, giving it higher creep strength above 871°C (1600°F), oxidation resistance to 1149°C (2100°F) versus 1093°C for X, premier nitriding resistance, and better thermal stability with no sigma or Laves phase after 16,000 hours. Lower thermal expansion reduces thermal fatigue in cyclic service. In many new combustor designs, 230-W has replaced HASTELLOY X.
Why is HAYNES 230-W Recommended for Thick-Section Cobalt Alloy Welds instead of Matching Cobalt Filler?
Cobalt alloy weldments in thick sections (>9.5 mm / 3/8″) are prone to hot cracking due to the wide solidification range of cobalt-base fillers. HAYNES 230-W is a nickel-base filler with better hot cracking resistance, and its high-temperature oxidation resistance makes it metallurgically compatible with HAYNES 188 and HAYNES 25 base metals.
Can HAYNES 230-W Welding Wire be used for SMAW (Stick) Welding?
HAYNES 230-W is available as bare wire/rod (AMS 5839, AWS A5.14 ERNiCrWMo-1) for GTAW and GMAW, and as coated electrodes (AWS A5.11 ENiCrWMo-1, UNS W86231) for SMAW. Unlike HAYNES 188 and HAYNES 25, which share a single electrode, 230-W has its own dedicated SMAW electrode with matching composition.
What makes HAYNES 230 Thermally Stable, and Why does it Matter for Welding?
HAYNES 230 achieves stability from the tungsten-rich M₆C and M₂₃C₆ carbides that resist overaging. After 16,000 hours at 649–870°C, no sigma, mu, or Laves phases form. For fabricators, this means no mandatory PWHT, no ductility loss during thermal cycles, and no risk of in-service embrittlement.
Does HAYNES 230-W Welding Wire Require Preheat or PWHT?
No preheat is required. Room temperature is specified. Interpass must stay below 93°C (200°F). PWHT is not generally required. If solution annealing is needed, heat to 1177–1246°C and rapidly cool.
When should you not use HAYNES 230-W Welding Wire?
Do not use for reducing acid service (HCl, H₂SO₄). Select HASTELLOY C-276 (ERNiCrMo-4) or C-22 (ERNiCrMo-10) instead. It is not economical for general dissimilar welding, where ERNiCrMo-3 (Inconel 625) would suffice. Avoid excessive weaving. Use stringer beads and maintain interpass below 93°C.
