What is N06210-CW?
N06210-CW is N06210 supplied in the CW condition — spring-temper strip and hard-drawn tube for springs, clips and thin-wall parts that will not see high temperature. N06210-CW has a yield strength of 780 MPa (113 ksi) and a tensile strength of 980 MPa (142 ksi) — stronger than 83% of nickel alloy grades. Elongation at break is 12% and the elastic modulus is 208 GPa (30.2 Msi). N06210-CW has a density of 7.9 g/cm³ (0.285 lb/in³), lighter than 92% of nickel alloy grades. It melts at 1,350°C (2,462 °F). SA is the default condition FabDigit quotes; CW is available on request or by drawing note.

Working with N06210-CW
Is N06210 easy to machine?
Machine like a gummy solid-solution nickel alloy: rigid setup, positive-rake sharp carbide or ceramic tooling, low speed and heavy positive feed to cut under the work-hardened layer, flood high-pressure coolant, never dwell.
Can N06210 be welded?
Readily joined by GTAW/GMAW/PAW with matching or Ni-Cr filler; keep interpass temperature low, restrict heat input to limit grain growth, no preheat needed, and clean off all oxide/sulphur-bearing contaminants before welding.
Can N06210 be formed, bent or molded?
Cold formable but work-hardens rapidly — allow generous bend radii and interstage anneals near 1100 °C with rapid cooling; hot work in the roughly 1150–1200 °C range and finish above 950 °C.
What surface finishes work on N06210?
Not anodisable; pickle in HNO3-HF or grit blast plus pickle to remove the tenacious high-temperature scale, then passivate, grind or electropolish for a clean furnace-ready surface.

N06210-CW — frequently asked
What is N06210-CW used for?
N06210-CW is typically used for furnace muffles, radiant tubes, heat-treating fixtures and combustion equipment. In short: 1150 °C furnace alloy; nitridation-resistant Ni-Cr-Fe; solid-solution, no ageing needed.
What is the yield strength of N06210-CW?
N06210-CW has a typical yield strength of 780 MPa (113 ksi) and a tensile strength of 980 MPa (142 ksi) — stronger than 83% of nickel alloy grades. Strength varies by condition: see the 5 listed tempers.
Is N06210-CW easy to machine?
Not especially — machinability is rated poor (16/100, worse than 71% of nickel alloy grades). Machine like a gummy solid-solution nickel alloy: rigid setup, positive-rake sharp carbide or ceramic tooling, low speed and heavy positive feed to cut under the work-hardened layer, flood high-pressure coolant, never dwell.
Can N06210-CW be welded?
Yes — weldability is rated good (55/100). Readily joined by GTAW/GMAW/PAW with matching or Ni-Cr filler; keep interpass temperature low, restrict heat input to limit grain growth, no preheat needed, and clean off all oxide/sulphur-bearing contaminants before welding.
What surface finishes work on N06210-CW?
Not anodisable; pickle in HNO3-HF or grit blast plus pickle to remove the tenacious high-temperature scale, then passivate, grind or electropolish for a clean furnace-ready surface.
Can N06210-CW be formed, bent or molded?
Cold formable but work-hardens rapidly — allow generous bend radii and interstage anneals near 1100 °C with rapid cooling; hot work in the roughly 1150–1200 °C range and finish above 950 °C.
What is the maximum service temperature of N06210-CW?
N06210-CW is rated for continuous use to about 500°C (932 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between N06210-SA and N06210-CW?
SA is the default condition — standard supply condition for all product forms: maximum ductility, homogeneous solid solution, best creep and oxidation performance. CW: spring-temper strip and hard-drawn tube for springs, clips and thin-wall parts that will not see high temperature. Yield strength is 320 MPa in SA versus 780 MPa in CW.
