Working with N06060-HF
Is N06060 easy to machine?
Gummy and strongly work-hardening: use rigid setups, positive-rake carbide, low speed (20–35 m/min) with heavy constant feed, flood coolant, and never dwell in the cut.
Can N06060 be welded?
Readily welded by GTAW/GMAW/SMAW with ERNiCr-3 / ENiCrFe-3 type filler; keep interpass below ~150 °C, use low heat input and clean surfaces to avoid sulphur and hot cracking; no post-weld heat treatment normally required.
Can N06060 be formed, bent or molded?
Excellent cold formability in the annealed temper but high springback and roughly 2× the press load of austenitic stainless; hot work at 870–1200 °C and re-anneal after heavy cold reduction.
What surface finishes work on N06060?
Not anodisable — pickle in HNO3/HF or grit-blast plus passivate, then abrasive polish or electropolish; electroless nickel and precious-metal plating adhere well after activation.

N06060-HF — frequently asked
What is N06060-HF used for?
N06060-HF is typically used for high-temperature process equipment, furnace fixtures and chemical processing components. In short: weldable 600-type Ni-Cr-Fe; good cold formability; 1000 °C service capability.
What is the yield strength of N06060-HF?
N06060-HF has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 640 MPa (92.8 ksi) — weaker than 78% of nickel alloy grades. Strength varies by condition: see the 7 listed tempers.
Is N06060-HF easy to machine?
Not especially — machinability is rated poor (19/100, worse than 52% of nickel alloy grades). Gummy and strongly work-hardening: use rigid setups, positive-rake carbide, low speed (20–35 m/min) with heavy constant feed, flood coolant, and never dwell in the cut.
Can N06060-HF be welded?
Yes — weldability is rated very good (78/100). Readily welded by GTAW/GMAW/SMAW with ERNiCr-3 / ENiCrFe-3 type filler; keep interpass below ~150 °C, use low heat input and clean surfaces to avoid sulphur and hot cracking; no post-weld heat treatment normally required.
What surface finishes work on N06060-HF?
Not anodisable — pickle in HNO3/HF or grit-blast plus passivate, then abrasive polish or electropolish; electroless nickel and precious-metal plating adhere well after activation.
Can N06060-HF be formed, bent or molded?
Excellent cold formability in the annealed temper but high springback and roughly 2× the press load of austenitic stainless; hot work at 870–1200 °C and re-anneal after heavy cold reduction.
What is the maximum service temperature of N06060-HF?
N06060-HF is rated for continuous use to about 1,000°C (1,832 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between N06060-ANN and N06060 Spring?
ANN is the default condition — standard stocked condition for plate, sheet, tube and bar — best ductility, formability and corrosion resistance. Spring: for springs, mesh and formed clips needing maximum strength; ductility and formability are minimal. Yield strength is 275 MPa in ANN versus 950 MPa in Spring.
