Working with N06219 CD-SR
Is N06219 easy to machine?
Rigid setups, positive-rake carbide, heavy constant feed and flood coolant; low surface speed (20–35 m/min) to avoid work hardening and never dwell in the cut.
Can N06219 be welded?
GTAW/GMAW with matching Ni-Cr-Mo filler, low heat input, interpass under ~120 °C, no preheat or PWHT; keep weld pool clean to avoid hot cracking and grind out heat tint before service.
Can N06219 be formed, bent or molded?
Very ductile but high work-hardening rate — expect 2× the press force of 304 stainless, use generous radii and intermediate solution anneals for severe draws.
What surface finishes work on N06219?
Pickle (HNO3-HF) or abrasive-blast plus passivation to restore the chromium oxide film; electropolishing gives best crevice-corrosion performance; not anodizable.

N06219 CD-SR — frequently asked
What is N06219 CD-SR used for?
N06219 CD-SR is typically used for chemical reactors, flue-gas desulfurization, acid handling piping and pulp bleaching equipment. In short: top-tier wet corrosion resistance; very ductile, hard to machine; weldable without PWHT.
What is the yield strength of N06219 CD-SR?
N06219 CD-SR has a typical yield strength of 620 MPa (89.9 ksi) and a tensile strength of 900 MPa (131 ksi) — stronger than 81% of nickel alloy grades. Strength varies by condition: see the 5 listed tempers.
Is N06219 CD-SR easy to machine?
Not especially — machinability is rated poor (22/100, better than 64% of nickel alloy grades). Rigid setups, positive-rake carbide, heavy constant feed and flood coolant; low surface speed (20–35 m/min) to avoid work hardening and never dwell in the cut.
Can N06219 CD-SR be welded?
Yes — weldability is rated very good (76/100). GTAW/GMAW with matching Ni-Cr-Mo filler, low heat input, interpass under ~120 °C, no preheat or PWHT; keep weld pool clean to avoid hot cracking and grind out heat tint before service.
What surface finishes work on N06219 CD-SR?
Pickle (HNO3-HF) or abrasive-blast plus passivation to restore the chromium oxide film; electropolishing gives best crevice-corrosion performance; not anodizable.
Can N06219 CD-SR be formed, bent or molded?
Very ductile but high work-hardening rate — expect 2× the press force of 304 stainless, use generous radii and intermediate solution anneals for severe draws.
What is the maximum service temperature of N06219 CD-SR?
N06219 CD-SR is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between N06219-SA and N06219-CW?
SA is the default condition — standard corrosion-service condition for plate, sheet, bar, pipe and fittings; maximum ductility and corrosion resistance. CW: choose for fasteners, shafts and springs where higher strength is needed and full annealed corrosion performance is not critical. Yield strength is 380 MPa in SA versus 760 MPa in CW.
