What is ENiCrMo-14?
ENiCrMo-14 is the covered manual-arc electrode counterpart to ERNiCrMo-14 wire (UNS W86686), used for welding superalloy equipment in extreme chloride and acid service. As-welded deposits give roughly 490 MPa yield, 780 MPa tensile, 40 % elongation and 92 HRB, with a corrosion rating of 96 and service to 400 °C; PWHT is normally not required. The deposit work-hardens strongly and is slow to machine, and consumable cost is high. ENiCrMo-13 covers similar duty where Alloy 59 chemistry is specified. ENiCrMo-14 has a density of 8.73 g/cm³ (0.315 lb/in³), heavier than 77% of nickel alloy grades. It melts at 1,338°C (2,440 °F). ENiCrMo-14 has a yield strength of 490 MPa (71.1 ksi) and a tensile strength of 780 MPa (113 ksi) — stronger than 71% of nickel alloy grades. Elongation at break is 40% and the elastic modulus is 205 GPa (29.7 Msi).

Working with ENiCrMo-14
Is ENiCrMo-14 easy to machine?
Deposit work-hardens strongly — use sharp carbide, heavy positive rake, low speed / high feed, rigid setup and flood coolant; grinding of weld caps needs non-ferrous wheels.
Can ENiCrMo-14 be welded?
SMAW DCEP, stringer beads, low heat input (<1.5 kJ/mm) and interpass ≤150 °C; redry electrodes ~250–300 °C, clean between passes, no PWHT normally required.
Can ENiCrMo-14 be formed, bent or molded?
Not a wrought product form; deposits are ductile and can tolerate weld-repair and light peening but should not be cold-worked heavily.

What surface finishes work on ENiCrMo-14?
Pickle/passivate or blast with clean non-iron media then final brush/polish; never anodize — protect surface from iron contamination for full corrosion performance.

ENiCrMo-14 — frequently asked
What is ENiCrMo-14 used for?
ENiCrMo-14 is typically used for manual repair of pollution control equipment, extreme corrosion service field welding, scrubber and absorber tower welds, chloride-bearing process vessels, acid process piping repairs and weld overlay on carbon steel components. In short: alloy 686 covered electrode; chloride and acid service; corrosion rating 96.
What is the yield strength of ENiCrMo-14?
ENiCrMo-14 has a typical yield strength of 490 MPa (71.1 ksi) and a tensile strength of 780 MPa (113 ksi) — stronger than 71% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ENiCrMo-14 easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Deposit work-hardens strongly — use sharp carbide, heavy positive rake, low speed / high feed, rigid setup and flood coolant; grinding of weld caps needs non-ferrous wheels.
Can ENiCrMo-14 be welded?
Yes — weldability is rated excellent (88/100). SMAW DCEP, stringer beads, low heat input (<1.5 kJ/mm) and interpass ≤150 °C; redry electrodes ~250–300 °C, clean between passes, no PWHT normally required.

Not a wrought product form; deposits are ductile and can tolerate weld-repair and light peening but should not be cold-worked heavily.
What is the maximum service temperature of ENiCrMo-14?
ENiCrMo-14 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ENiCrMo-14-AW and ENiCrMo-14-SA?
AW is the default condition — standard condition for corrosion-service joints and overlays; use low heat input and interpass ≤150 °C. SA: used when clad/overlaid components receive a full solution anneal; homogenises the dendritic deposit, softens it and restores maximum corrosion resistance. Yield strength is 490 MPa in AW versus 380 MPa in SA.
