Working with N06110 HF-A
Is N06110 easy to machine?
Machine like alloy C-276: rigid setup, positive-rake sharp carbide, low surface speed (~15–25 m/min), heavy constant feed to cut under the work-hardened layer, and flood high-pressure coolant.
Can N06110 be welded?
Readily GTAW/GMAW/PAW welded with matching or over-alloyed Ni-Cr-Mo filler; low heat input, interpass <150 °C, no preheat or PWHT, and remove heat tint by pickling to restore passivity.
Can N06110 be formed, bent or molded?
Cold forms well in the annealed state but work-hardens rapidly — allow generous bend radii and interstage solution anneals; hot work 1150–950 °C followed by rapid water quench.
What surface finishes work on N06110?
Pickle/passivate or electropolish after fabrication; not anodizable — for wear surfaces use nitriding-free coatings such as HVOF carbide or electroless nickel.

N06110 HF-A — frequently asked
What is N06110 HF-A used for?
N06110 HF-A is typically used for furnace and heat-treatment components, high-temperature fasteners and process industry fixtures. In short: high-strength Ni-Cr-Fe grade; corrosion score 90; 650 °C service limit.
What is the yield strength of N06110 HF-A?
N06110 HF-A has a typical yield strength of 370 MPa (53.7 ksi) and a tensile strength of 770 MPa (112 ksi) — weaker than 55% of nickel alloy grades. Strength varies by condition: see the 5 listed tempers.
Is N06110 HF-A easy to machine?
Not especially — machinability is rated poor (16/100, worse than 71% of nickel alloy grades). Machine like alloy C-276: rigid setup, positive-rake sharp carbide, low surface speed (~15–25 m/min), heavy constant feed to cut under the work-hardened layer, and flood high-pressure coolant.
Can N06110 HF-A be welded?
Yes — weldability is rated very good (70/100). Readily GTAW/GMAW/PAW welded with matching or over-alloyed Ni-Cr-Mo filler; low heat input, interpass <150 °C, no preheat or PWHT, and remove heat tint by pickling to restore passivity.
What surface finishes work on N06110 HF-A?
Pickle/passivate or electropolish after fabrication; not anodizable — for wear surfaces use nitriding-free coatings such as HVOF carbide or electroless nickel.
Can N06110 HF-A be formed, bent or molded?
Cold forms well in the annealed state but work-hardens rapidly — allow generous bend radii and interstage solution anneals; hot work 1150–950 °C followed by rapid water quench.
What is the maximum service temperature of N06110 HF-A?
N06110 HF-A 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 N06110-SA and N06110 CW-HS?
SA is the default condition — standard stocked condition for plate, sheet, tube and bar — maximum corrosion resistance and ductility. CW-HS: maximum-strength condition for springs, wire and small pins; ductility and cold formability are largely exhausted. Yield strength is 390 MPa in SA versus 1,100 MPa in CW-HS.
