Working with NiCr60/16 HR-ANN

Is NiCr60/16 easy to machine?

Machine like an austenitic Ni alloy: rigid setup, sharp positive-rake carbide, low speed (~15–25 m/min) with heavy feed and flood coolant to avoid work hardening and glazing.

Can NiCr60/16 be welded?

Resistance/spot welding and TIG with matching NiCr60 or ERNiCr-3 filler work well; keep heat input low, avoid sulfur-bearing contaminants and remove oxide before welding.

Can NiCr60/16 be formed, bent or molded?

Annealed material coils, bends and stamps readily but work-hardens fast — use generous radii, interstage anneals at 900–1000 °C and lubricated dies for deep drawing.

What surface finishes work on NiCr60/16?

Not anodizable; supplied bright, matte or pre-oxidized. Controlled pre-oxidation at 900–1000 °C in air gives the protective Cr2O3 film; electropolish or pickle in HNO3-HF blends to clean before brazing.

NiCr60/16 HR-ANN — frequently asked

What is NiCr60/16 HR-ANN used for?

NiCr60/16 HR-ANN is typically used for domestic appliance heating elements, low-cost furnace elements, oven and toaster element coils, tubular heater windings, hair dryer and fan heater coils and heat-sealing bar strip. In short: lower-cost nichrome grade; fe-bearing 60/16 chemistry; 1100 °C element wire.

What is the yield strength of NiCr60/16 HR-ANN?

NiCr60/16 HR-ANN has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 650 MPa (94.3 ksi) — weaker than 78% of nickel alloy grades. Strength varies by condition: see the 4 listed tempers.

Is NiCr60/16 HR-ANN easy to machine?

Not especially — machinability is rated poor (28/100, better than 82% of nickel alloy grades). Machine like an austenitic Ni alloy: rigid setup, sharp positive-rake carbide, low speed (~15–25 m/min) with heavy feed and flood coolant to avoid work hardening and glazing.

Can NiCr60/16 HR-ANN be welded?

Yes — weldability is rated good (64/100). Resistance/spot welding and TIG with matching NiCr60 or ERNiCr-3 filler work well; keep heat input low, avoid sulfur-bearing contaminants and remove oxide before welding.

What surface finishes work on NiCr60/16 HR-ANN?

Not anodizable; supplied bright, matte or pre-oxidized. Controlled pre-oxidation at 900–1000 °C in air gives the protective Cr2O3 film; electropolish or pickle in HNO3-HF blends to clean before brazing.

Can NiCr60/16 HR-ANN be formed, bent or molded?

Annealed material coils, bends and stamps readily but work-hardens fast — use generous radii, interstage anneals at 900–1000 °C and lubricated dies for deep drawing.

What is the maximum service temperature of NiCr60/16 HR-ANN?

NiCr60/16 HR-ANN is rated for continuous use to about 1,050°C (1,922 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between NiCr60/16-ANN and NiCr60/16-HD?

ANN is the default condition — standard stocked condition for coiling heating elements and forming — maximum ductility, stable resistance. HD: for resistors, precision springs and fine wire needing high tensile strength and straightness; anneals out above ~600 °C in service. Yield strength is 350 MPa in ANN versus 850 MPa in HD.
