Duranickel 301 Tube

An age-hardened alloy that combines the excellent corrosion resistance characteristics of Nickel 200 with the added advantages of greater strength and hardness. The alloy is used for springs requiring high electrical conductivity,parts of equipment requiring good thermal conductivity and magnetostrictive units, which are operated under stress conditions in which the fatigue strength of Nickel 200 is inadequate.STANDARD PRODUCT FORMSRound bar and wire.MAJOR SPECIFICATIONSUNS N03301LIMITING CHEMICAL COMPOSITION, %Nia.........93.0 min.Mn........0.50 max.Ti....... 0.25 – 1.00aPlus Co.Cu.........0.25 max.Fe..........0.60 max.C............0.30 max.Si...........1.00 max.S............0.01 max.Al........4.00 – 4.75PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity, Ib/in3 (g/cm3)............................................ 0.296 (8.19)Melting Range, °F (°C)..............2550 – 2620 (1400 – 1440)Specific Heat, Btu/lb•°F (J/kg•°C)....................... 0.104 (435)Curie TemperatureA, °F (°C)......................................... 200 (95)Permeability at 200 OerstedA (15.9 kA/m)....................10.58Coefficient of ExpansionA, 10-6 in/in•°F (μm/m•°C)70-200°F (21–93°C).........................7.2 (13.0)70-500°F (21–260°C)......................7.7 (13.9)70-800°F (21–427°C)..................... 8.0 (14.4)70-1000°F (21–538°C)................... 8.2 (14.8)70-1200°F (21–650°C)................... 8.5 (15.3)70-1400°F (21–760°C)................... 8.8 (15.9)Thermal ConductivityA, Btu•in/ft2•h•°F (W/m•°C)....165 (23.8)Electrical ResistivityA, ohm•circ mil/ft (μΩ•m)..... 255 (0.424)Young’s ModulusA, 106 psi (GPa)..............................30.0 (207)Poisson’s RatioA....................................................................... 0.31HardnessA, HRC..................................................................30 – 42ARoom temperature, as aged.TYPICAL MECHANICAL PROPERTIES
