Material Characteristics

Density	about 8.4g/cm³
Resistivity	1.28 μΩ·m (20℃)
Temperature Range	Continuous Service 1150℃~1300℃, Short-Term Peak 1350℃

Key Advantages

● Dual High-Content Reinforcement:

30% Cr + 70% Ni synergy provides triple protection against carburization, sulfidation, and extreme-temperature oxidation.

● Extreme Mechanical Strength:

Maintains ≥200 MPa tensile strength at 1300℃, resisting high-temperature creep deformation.

● Superior Chemical Inertness:

Corrosion rate ＜0.1 mm/year in strong acids, alkalis, and halogen-containing atmospheres.

Typical Applications

● Chemical Reactors:

Heating elements and catalyst carrier wires for ethylene cracking furnaces and ammonia synthesis reactors.

● Nuclear Energy Systems:

Heating wires for reactor control rods, resistance components in high-temperature cooling circuits.

● Special Metallurgy:

Radiant tubes and heating coils for tungsten-molybdenum sintering furnaces and superalloy melting systems.
