Key Performance Features:
Ultra-High Temperature Strength: Retains 75% of room temperature tensile strength at 1000°C.
Oxidation Resistance: Forms a self-healing Al2O3-Cr2O3-Ta2O5 composite oxide layer, reducing oxidation rates by 65% compared to traditional superalloys.
Thermal Fatigue Life: Withstands 15,000+ thermal cycles between ambient and 1100°C.
Precision Fabrication: Achieves micro-bore dimensions down to 0.08mm ID with ±0.0015mm tolerance.
Performance Advantages
Thermal Efficiency: 30% improvement in heat transfer coefficient vs Haynes 282.
Corrosion Resistance: Withstands 1000h in 90% H2O-10% O2 at 1100°C.
Flow Dynamics: 40% reduction in turbulence-induced pressure losses.
Temperature Adaptability: Stable operation from -253°C (liquid hydrogen) to 1200°C.
