Working with NiCr26MoW
Is NiCr26MoW easy to machine?
Machine like alloy 600/625: rigid setup, sharp positive-rake carbide, low surface speed (20–35 m/min), heavy constant feed to cut below the work-hardened layer, and flood coolant.
Can NiCr26MoW be welded?
Readily GTAW/GMAW/SMAW welded with matching or over-alloyed Ni-Cr-Mo filler; keep interpass below ~150 °C, low heat input, no preheat and no PWHT normally required, clean surfaces free of sulphur and grease.
Can NiCr26MoW be formed, bent or molded?
Cold forms well but with high loads and rapid work hardening — allow interstage anneals at 1080–1150 °C with rapid cooling; hot work in the 1150–950 °C range.
NiCr26MoW 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 NiCr26MoW?
Pickle or grit-blast plus passivate after hot work/welding to restore the chromium oxide film; not anodisable, and any protective coatings must tolerate the intended furnace temperature.

NiCr26MoW — frequently asked
What is NiCr26MoW used for?
NiCr26MoW is typically used for furnace muffles, radiant tubes, heat-treatment fixtures and industrial burner components. In short: service to 1150 °C; high-chromium furnace alloy; solid-solution, no ageing needed.
What is the yield strength of NiCr26MoW?
NiCr26MoW has a typical yield strength of 350 MPa (50.8 ksi) and a tensile strength of 730 MPa (106 ksi) — weaker than 60% of nickel alloy grades. Strength varies by condition: see the 5 listed tempers.
Is NiCr26MoW easy to machine?
Not especially — machinability is rated poor (22/100, better than 64% of nickel alloy grades). Machine like alloy 600/625: rigid setup, sharp positive-rake carbide, low surface speed (20–35 m/min), heavy constant feed to cut below the work-hardened layer, and flood coolant.
Can NiCr26MoW be welded?
Yes — weldability is rated very good (70/100). Readily GTAW/GMAW/SMAW welded with matching or over-alloyed Ni-Cr-Mo filler; keep interpass below ~150 °C, low heat input, no preheat and no PWHT normally required, clean surfaces free of sulphur and grease.
What surface finishes work on NiCr26MoW?
Pickle or grit-blast plus passivate after hot work/welding to restore the chromium oxide film; not anodisable, and any protective coatings must tolerate the intended furnace temperature.
Can NiCr26MoW be formed, bent or molded?
Cold forms well but with high loads and rapid work hardening — allow interstage anneals at 1080–1150 °C with rapid cooling; hot work in the 1150–950 °C range.
What is the maximum service temperature of NiCr26MoW?
NiCr26MoW is rated for continuous use to about 1,150°C (2,102 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between NiCr26MoW-SA and NiCr26MoW-CW?
SA is the default condition — standard delivery condition for sheet, plate, bar and tube; best ductility, corrosion resistance and high-temperature stability. CW: use where higher room-temperature strength or spring temper is needed; not for service above ~600 °C, where recrystallisation removes the cold-work benefit. Yield strength is 350 MPa in SA versus 800 MPa in CW.
