Inconel 601 Filler Wire

Metracore Alloys Private Limited supplies Inconel 601 filler wire to fabricators, furnace builders and plant maintenance contractors across India and overseas markets, holding stock in both TIG rod and MIG spool form. The consumable is classified as AWS A5.14 / ASME SFA-5.14 ERNiCrFe-11 under UNS N06601. Diameters from 0.8 mm to 3.2 mm cover thin sheet work through to heavy-section retorts.

Inconel 601 is a nickel-chromium alloy with a deliberate aluminium addition. Nickel sits between 58.0 and 63.0%, chromium between 21.0 and 25.0%, and aluminium between 1.00 and 1.70%. Iron makes up the balance. That aluminium content explains why the grade behaves differently from other nickel-chromium-iron consumables at temperature: it forms an alumina subscale beneath the chromia layer, which resists spallation under thermal cycling and slows carbon ingress into the weld.

Typical all-weld-metal tensile strength reaches 648 MPa (94 ksi), with elongation near 40% as welded. Deposited metal matches the base alloy for oxidation and aqueous corrosion resistance. Above 1150°C (2100°F) and in atmospheres carrying hydrogen sulphide or sulphur dioxide, GTAW with 601 filler remains the recommended joining route. Heat treatment plants, industrial furnaces, petrochemical units, power stations and aerospace thermal hardware all draw on it. Every batch ships with a mill test certificate traceable to the heat number. Confirm diameter availability with our team before releasing an order.

WHY CHOOSE METRACORE ALLOYS FOR INCONEL 601 FILLER WIRE?

Technical Details of Inconel 601 Filler Wire

Chemical Composition of Inconel 601 Filler Wire

Limits below follow AWS A5.14 for ERNiCrFe-11. Chromium builds the primary oxide barrier. Aluminium forms the alumina subscale that survives repeated heating and cooling.

ElementContent (%)
Nickel (Ni)58.0 to 63.0
Chromium (Cr)21.0 to 25.0
Iron (Fe)Balance
Aluminium (Al)1.00 to 1.70
Carbon (C)0.10 max
Manganese (Mn)1.00 max
Silicon (Si)0.50 max
Copper (Cu)1.00 max
Sulphur (S)0.015 max
Phosphorus (P)0.030 max

Eight characteristics drive the selection of this consumable:

  • Oxidation resistance: The alumina subscale formed by 1.00 to 1.70% aluminium adheres well and resists spallation through repeated heating and cooling cycles.
  • High-temperature strength: Weld metal holds load-bearing capacity where austenitic stainless steel deposits creep.
  • Carburisation resistance: That same alumina layer slows carbon diffusion into the weld in carbon-rich furnace atmospheres.
  • Aqueous corrosion resistance: High nickel content carries the deposit through wet conditions after shutdown.
  • Thermal stability: A face-centred-cubic solid solution resists structural change over long exposure.
  • Ductility: Elongation near 40% tolerates thermal strain.
  • Sulphur tolerance: Deposits withstand hydrogen sulphide and sulphur dioxide exposure.
  • Weldability: Preheat isn’t normally needed, and no post-weld heat treatment is required to obtain the oxidation and carburisation resistance. Interpass temperature should be held below 150°C.

Five designations identify this consumable on purchase and procedure documents.

  • Inconel 601 is the name of the parent nickel-chromium-aluminium alloy that the filler is formulated to match. Weld metal deposited from it holds oxidation and corrosion resistance comparable to the base material.
  • UNS N06601 is the Unified Numbering System identifier shared by the base alloy and its matching filler classification.
  • W.Nr. 2.4851 applies to alloy 601 in wrought forms. The consumable carries W.Nr. 2.4626, a distinction worth checking against European documentation.
  • AWS A5.14 ERNiCrFe-11 governs the chemistry and manufacture of the bare wire and rod.
  • ASME SFA-5.14 mirrors that classification for code work, and Section IX assigns the consumable to F-Number 43.

The applicable standard depends on filler form, welding process and governing code.

  • AWS A5.14 sets composition, manufacture and packaging requirements for bare nickel-alloy welding rods.
  • ASME SFA-5.14 adopts that specification into Section II, Part C, bringing the consumable under the Boiler and Pressure Vessel Code.
  • ASME Section IX F-No. 43 groups it for welder and procedure qualification.
  • EN ISO 18274:2023 designates the wire S Ni 6601 (NiCr23Fe15Al) across European projects.
  • BS 2901 NA 49 is used on legacy British drawings. The standard has been withdrawn and replaced by BS EN ISO 18274, so quote the ISO designation on new work.
  • Project specifications sit above all of these. Refinery clients often restrict residual elements, and those limits must be met at the mill before wire is drawn.

Diameters and packaging vary by process.

  • GTAW rods: 1.6 mm, 2.0 mm, 2.4 mm and 3.2 mm in cut lengths of 915 mm or 1000 mm, boxed in 5 kg or 10 kg units.
  • GMAW spools: 0.8 mm through 1.6 mm wire on precision-layer reels.
  • Coil supply: suits mechanised welding cells.

Inconel 601 Filler Wire FAQs

What Is Inconel 601 Filler Wire?

Inconel 601 filler wire is a nickel-chromium-aluminium welding consumable classified as AWS A5.14 ERNiCrFe-11. It joins alloy 601 to itself and to other high-temperature alloys.

The UNS number is N06601, covering both the base alloy and the matching filler classification.

Use ERNiCrFe-11 for matching-composition welds. ERNiCr-3 and ERNiCrMo-3 serve some dissimilar joints, though neither matches 601 for oxidation resistance above 1150°C.

Oxidation resistance, carburisation resistance, sulphur tolerance and high-temperature strength drive most selections.

Spooled wire is available from 0.8 mm to 1.6 mm. Cut rods are stocked from 1.6 mm to 3.2 mm in 915 mm and 1000 mm lengths.

Inconel 601 filler wire can be used for TIG welding, and GTAW is its primary application above 1150°C.

GTAW is the process AWS lists for this classification. GMAW is workable with spooled 601 wire under certain conditions, provided a qualified procedure covers it.

Furnace fabrication, heat treatment plants, petrochemical units, power stations and aerospace thermal hardware account for most demand.

AWS A5.14 and ASME SFA-5.14 govern the classification, with ISO 18274 and BS 2901 NA 49 applying to European and British specifications.

A mill test certificate with heat and lot traceability accompanies each consignment, and conformity certificates or third-party inspection reports are arranged on request.
