Haynes 230 Filler Wire
Metracore Alloys Private Limited supplies, stocks and exports Haynes 230 filler wire to fabricators, EPC contractors and plant maintenance teams in India and overseas markets. The filler wire is also designated as 230-W and classified as AWS A5.14 / ASME SFA-5.14 ERNiCrWMo-1 under UNS N06231. Stock is available in MIG spools, TIG cut lengths, reels and coils, covering 0.76 mm to 4.70 mm.
Haynes 230 is a nickel-chromium-tungsten-molybdenum alloy built for sustained service at elevated temperatures. Chromium at 20.0 to 24.0% forms the protective oxide film. Tungsten at 13.0 to 15.0% in the deposit stiffens the matrix against creep. A small lanthanum addition anchors the oxide film so it resists spalling through thermal cycling. Deposited weld metal meets a minimum tensile strength of 760 MPa (110 ksi).
Buyers specify this filler metal for oxidation resistance, thermal stability and resistance to carburising atmospheres. Gas turbine combustors, furnace internals, heat-treatment fixtures and reformer hardware all draw on those characteristics. The wire also joins UNS N06617.
Every consignment carries heat and lot traceability plus an EN 10204 3.1 certificate. Request the current diameter availability before finalising your welding procedures.

Tungsten stiffens the nickel matrix against dislocation movement, which maintains strength at temperature. Chromium builds the chromia film that resists oxidation and carburising gas attack. Carbon between 0.05 and 0.15% forms primary carbides that pin grain boundaries during long thermal exposure. Lanthanum, capped at 0.050%, anchors the oxide scale so it does not spall under cycling. Sulphur is held to 0.015% max and phosphorus to 0.03% max, since both promote hot cracking in nickel weld metal.
Properties of Haynes 230 Filler Wire
Seven characteristics decide where ERNiCrWMo-1 deposits earn their place. Strength and scale behaviour at temperature come first, followed by resistance to aggressive process gas, structural stability over long exposure, and ease of fabrication.
- High-temperature strength: tungsten and molybdenum hold the deposit through extended elevated-temperature exposure.
- Oxidation resistance: the chromia scale, stabilised by lanthanum, resists spalling under thermal cycling.
- Carburisation resistance: low iron and a stable oxide film limit carbon ingress in reducing atmospheres.
- Nitriding resistance: deposits perform in ammonia and nitrogen-rich process gas.
- Thermal stability: the solid-solution structure resists embrittling phase formation over long service.
- Creep resistance: solid-solution tungsten and molybdenum, backed by carbide precipitates at the grain boundaries, resist slow deformation under sustained load.
- Weldability: the wire deposits by GTAW and GMAW with no preheat and interpass held below 93°C.
Haynes 230 Filler Wire Welding Processes
Haynes 230 Filler Wire Standards
Five standards apply here. The governing document depends on the filler form, welding process, base material and project requirements.
- UNS N06231 identifies the filler metal chemistry in North American procurement systems.
- AWS A5.14 classifies the bare wire as ERNiCrWMo-1, fixing its composition limits. The 760 MPa deposit minimum comes with the AMS 5839 route and the producer datasheet.
- ASME SFA-5.14 mirrors it for pressure equipment built to the Boiler and Pressure Vessel Code.
- AMS 5839 covers bare welding wire and rod for aerospace procurement, where lot control is tight.
- EN ISO 18274 S Ni 6231 designates the equivalent solid wire in European classification.
Customer specifications sit above these whenever a client imposes extra testing, packaging or approval conditions.
