Key Performance Features:
Carburization Resistance: Maintains ductility after 1000h in carburizing atmospheres at 900°C.
Thermal Fatigue Resistance: Withstands over 7,000 thermal cycles between 20°C and 950°C without cracking.
Creep Strength: Maintains 80% of room temperature tensile strength at 850°C.
Fabrication Precision: Achieves inner diameters as small as 0.25mm with ±0.004mm tolerance.
Performance Advantages
Thermal Cycling: 2x longer service life than Incoloy 800H in cyclic carburization tests.
Corrosion Resistance: Withstands 1000h in 50% CO-50% H2 at 900°C with <0.1mm penetration.
Flow Efficiency: 18% lower pressure drop compared to ceramic alternatives.
Temperature Range: Continuous operation from -196°C to 950°C.
