Cold Drawn High temperature Alloy GH4169 Tube introduce
Cold-drawn GH4169 (Inconel 718) high-temperature alloy tubing is a precipitation-hardening nickel-based alloy designed to achieve exceptional strength and corrosion resistance at temperatures up to 650°C. Its high-temperature performance is commonly used in aerospace, turbine engine, and nuclear energy applications. The cold-drawing process improves surface finish, dimensional accuracy, and material strength, while annealing is typically used to optimize microstructure and control grain size.

Why Choose Gnee Steel's GH4169 BA Tubing?
✅️Ultra-Clean Surface (Oxidation-Free): Hydrogen-protected annealing ensures zero oxidation or scaling. The tubing is ready for cleanroom applications upon delivery.
✅️Micro-Tolerances: We strictly control dimensions to within ±0.05mm tolerances, ensuring a perfect fit in high-pressure joints and rail welding.
✅️Enhanced Corrosion Resistance: The smooth, mirror-finish surface significantly reduces the effective surface area, preventing contaminant buildup and minimizing the risk of pitting corrosion.
✅️Superior Mechanical Properties: While achieving high surface quality, the tubing retains all the high-temperature strength and fatigue resistance of the GH4169 (Inconel 718) high-temperature alloy.

FAQ
Q: Can you provide BA tubes for semiconductor or cleanroom applications?
A: Yes, our BA GH4169 tubes are widely used in high-purity gas delivery. We provide additional ultra-sonic cleaning and specialized packaging to meet cleanroom standards.
Q: Does Bright Annealing affect the strength of Inconel 718?
A: Not at all. Bright Annealing is a thermal process that optimizes the grain structure for better ductility and surface finish while maintaining the alloy's core high-temperature mechanical properties.
Q: What is the maximum length for your high-precision BA tubes?
A: We provide straight lengths up to 6 meters, but for small diameter tubes, we can also supply them in seamless coils to minimize joints in long-distance fluid lines.
Q: How do you protect the surface during shipping?
A: Each BA tube is individually sleeved in plastic and packed in reinforced wooden crates or hard tubes to prevent any surface scratches or contamination during transit.
