Physical Properties

Density: 8.43 g/cm³

Melting Temperature Range: 1370 - 1430°C

Thermal Conductivity: 12.85 W/(m·°C) at 20°C, increasing with temperature-22.40 W/(m·°C) at 600°C and 31.60 W/(m·°C) at 1000°C.

Specific Heat Capacity: Varies with temperature.

Coefficient of Linear Expansion:

12.35 × 10⁻⁶ °C⁻¹ in the 20 - 200°C range

16.20 × 10⁻⁶ °C⁻¹ in the 20 - 1000°C range

Electrical Resistivity: Varies with temperature.

Magnetic Properties: Non-magnetic.


Mechanical Properties

Yield Strength:

Annealed state: 172 - 345 MPa (25 - 50 ksi)

Cold-drawn wire (1.6 - 6.4 mm, spring-tempered): 1035 - 1450 MPa (150 - 210 ksi)

Tensile Strength:

Nominal room-temperature: 520 - 1170 MPa (75 - 170 ksi)

Cold-worked wire: 1170 - 1520 MPa (170 - 220 ksi)

Elongation: 35% - 55% in the annealed state.

Impact Strength: Maintains good toughness at room temperature and does not exhibit a ductile-to-brittle transition at lower temperatures.

Fatigue Strength:

Affected by grain size and mechanical properties in high-speed rotating beam fatigue applications.

Minimal effect on low-cycle fatigue strength.

Creep Resistance: Excellent resistance to slow and gradual deformation over time, particularly at high temperatures.


Chemical Properties

Corrosion Resistance

Acid and Alkali Resistance:

The high nickel content provides excellent resistance in reducing environments and alkaline solutions.

Chromium enhances resistance to sulfur compounds and oxidation in high-temperature and corrosive environments.

Chloride Resistance:

With a minimum nickel content of 72%, the alloy is highly resistant to chloride-ion stress-corrosion cracking.

However, under high-temperature, high-strength caustic conditions or mercury exposure, stress-corrosion cracking may still occur.

Gas Resistance:

Exhibits good resistance to dry chlorine and hydrogen chloride gases, even at high temperatures.


Processability Properties

Formability: Suitable for both cold working and hot working.

Weldability: Can be joined using resistance welding, fusion welding, or brazing.

Machinability: Easily machinable in the hot-processed and annealed states.
