What is ENiCrCoMo-1?
ENiCrCoMo-1 (UNS W86117) is a Ni-Cr-Co-Mo covered electrode matching Haynes 230-type alloy chemistry, depositing weld metal with high creep strength and oxidation resistance up to 1100 °C. Typical as-welded properties are 430 MPa yield, 720 MPa tensile, 38% elongation and 210 HB, with a corrosion resistance score of 80. It is used for combustor and high-temperature furnace fabrication and for superalloy repair. Machinability is low (score 20), electrodes must be redried before use, and dilution from carbon or low-alloy steel has to be limited to avoid hot cracking; ENiCrFe-2 covers lower-temperature Ni-Cr-Fe joints. ENiCrCoMo-1 has a density of 8.36 g/cm³ (0.302 lb/in³), heavier than 54% of nickel alloy grades. It melts at 1,332°C (2,430 °F). ENiCrCoMo-1 has a yield strength of 430 MPa (62.4 ksi) and a tensile strength of 720 MPa (104 ksi) — stronger than 64% of nickel alloy grades. Elongation at break is 38% and the elastic modulus is 211 GPa (30.6 Msi).

Working with ENiCrCoMo-1
Is ENiCrCoMo-1 easy to machine?
Weld deposits machine like alloy 617 — low speed, heavy positive-rake carbide tooling, rigid setup and flood coolant; grind rather than mill where possible.
Can ENiCrCoMo-1 be welded?
Redry electrodes (300–350 °C) before use, weld DCEP with stringer beads, low heat input and interpass ≤150 °C; no preheat needed but keep dilution from carbon/low-alloy base metals low to avoid hot cracking.
Can ENiCrCoMo-1 be formed, bent or molded?
Not a wrought product form — the deposit is used as-welded; joint groove design should allow small beads and easy slag removal.
ENiCrCoMo-1 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 ENiCrCoMo-1?
Remove slag completely between passes, then wire-brush/pickle-passivate; the Al-bearing oxide must be ground off before any coating or braze operation.

ENiCrCoMo-1 — frequently asked
What is ENiCrCoMo-1 used for?
ENiCrCoMo-1 is typically used for gas turbine combustor welding, high-temperature furnace fabrication and aerospace superalloy repair. In short: highest-temperature Ni electrode; oxidation resistant to 1100 °C; superalloy repair filler.
What is the yield strength of ENiCrCoMo-1?
ENiCrCoMo-1 has a typical yield strength of 430 MPa (62.4 ksi) and a tensile strength of 720 MPa (104 ksi) — stronger than 64% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is ENiCrCoMo-1 easy to machine?
Not especially — machinability is rated poor (20/100, better than 53% of nickel alloy grades). Weld deposits machine like alloy 617 — low speed, heavy positive-rake carbide tooling, rigid setup and flood coolant; grind rather than mill where possible.
Can ENiCrCoMo-1 be welded?
Yes — weldability is rated excellent (85/100). Redry electrodes (300–350 °C) before use, weld DCEP with stringer beads, low heat input and interpass ≤150 °C; no preheat needed but keep dilution from carbon/low-alloy base metals low to avoid hot cracking.

Not a wrought product form — the deposit is used as-welded; joint groove design should allow small beads and easy slag removal.
What is the maximum service temperature of ENiCrCoMo-1?
ENiCrCoMo-1 is rated for continuous use to about 1,100°C (2,012 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ENiCrCoMo-1-AW and ENiCrCoMo-1-SA?
AW is the default condition — standard supply/qualification condition for the electrode: deposit used directly in the as-welded state for high-temperature piping and combustor repair. SA: choose when the fabrication receives a full solution anneal (e.g. weld-overlay clad plate or tube assemblies) to dissolve interdendritic carbides and restore ductility/creep uniformity. Yield strength is 430 MPa in AW versus 350 MPa in SA.
