Working with N06035-SA
Is N06035 easy to machine?
Machine like alloy 625/C-276: rigid setup, positive-rake carbide, heavy positive feed to cut under the work-hardened layer, low SFM and flood coolant.
Can N06035 be welded?
Readily GTAW/GMAW welded with matching G-35 filler; keep interpass below ~100 °C, low heat input, no preheat and no PWHT required for corrosion service.
Can N06035 be formed, bent or molded?
Very ductile but strongly work hardening — form hot at 950–1200 °C or cold with intermediate solution anneals at ~1120 °C followed by rapid quench.
What surface finishes work on N06035?
Pickle or grit-blast plus pickle to remove heat tint after welding/annealing; electropolishing gives the best passive surface. Not anodizable.

N06035-SA — frequently asked
What is N06035-SA used for?
N06035-SA is typically used for high-temperature furnace components, process heater tubing and heat-resistant fixtures. In short: furnace-atmosphere Ni-Cr alloy; very high corrosion resistance; difficult to machine.
What is the yield strength of N06035-SA?
N06035-SA has a typical yield strength of 360 MPa (52.2 ksi) and a tensile strength of 760 MPa (110 ksi) — weaker than 57% of nickel alloy grades. Strength varies by condition: see the 4 listed tempers.
Is N06035-SA easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Machine like alloy 625/C-276: rigid setup, positive-rake carbide, heavy positive feed to cut under the work-hardened layer, low SFM and flood coolant.
Can N06035-SA be welded?
Yes — weldability is rated very good (78/100). Readily GTAW/GMAW welded with matching G-35 filler; keep interpass below ~100 °C, low heat input, no preheat and no PWHT required for corrosion service.
What surface finishes work on N06035-SA?
Pickle or grit-blast plus pickle to remove heat tint after welding/annealing; electropolishing gives the best passive surface. Not anodizable.
Can N06035-SA be formed, bent or molded?
Very ductile but strongly work hardening — form hot at 950–1200 °C or cold with intermediate solution anneals at ~1120 °C followed by rapid quench.
What is the maximum service temperature of N06035-SA?
N06035-SA is rated for continuous use to about 650°C (1,202 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between N06035-SA and N06035-CD?
SA is the default condition — standard supply condition for plate, sheet, tube, pipe and bar; maximum corrosion resistance and ductility. CD: choose when higher strength and tight dimensional tolerance are needed and service is not in a sensitizing or highly aggressive crevice environment. Yield strength is 360 MPa in SA versus 720 MPa in CD.
