Product Description

GH3044 capillary tubes are engineered from a nickel-chromium-tungsten superalloy, specifically designed to excel in high-temperature oxidizing and carburizing environments. With a composition of 25% chromium, 15% tungsten, and balanced nickel, this alloy delivers exceptional thermal stability and corrosion resistance, making it ideal for precision fluid control in demanding applications.
 

Key Performance Features:

• Oxidation Resistance: Forms a continuous Cr2O3-Al2O3 protective layer, reducing oxidation rates by 60% compared to conventional alloys at 1100°C.

• Thermal Fatigue Resistance: Withstands over 8,000 thermal cycles between 20°C and 1000°C without cracking.

• Creep Strength: Maintains 85% of room temperature tensile strength at 900°C.

• Fabrication Precision: Achieves inner diameters as small as 0.2mm with ±0.003mm tolerance.

Performance Advantages

• Thermal Cycling: 2.5x longer service life than Haynes 230 in cyclic oxidation tests.

• Corrosion Resistance: Withstands 1000h in 90% N2-10% H2 at 1000°C with <0.1mm penetration.

• Flow Efficiency: 20% lower pressure drop compared to ceramic alternatives.

• Temperature Range: Continuous operation from -196°C to 1100°C.
