Our GH4169 (Inconel718) high-temperature tubes are built to power the future of jet engines, delivering unmatched strength and resilience in the most demanding environments. This nickel-based superalloy is a cornerstone for aerospace components, and we’re excited to showcase why it’s the perfect choice for jet engine parts, its role in industry trends, and how our expertise sets us apart.
What is GH4169 Alloy?
GH4169, also known as Inconel718, is a nickel-chromium superalloy designed for extreme conditions. Packed with niobium and molybdenum, it boasts incredible strength, fatigue resistance, and creep strength up to 700°C (and short-term peaks at 1000°C). Its robust oxide layer shields it from oxidation and corrosion, making it a go-to for jet engine components like turbine blades, discs, and exhaust systems. Whether forged, rolled, or 3D-printed, GH4169 delivers precision and durability.
Our GH4169 tubes are crafted using advanced techniques like laser powder bed fusion (LPBF), ensuring low porosity and a reproductive surface finish. We can also heat-treat the alloy through precipitation hardening to fine-tune its mechanical properties, giving you flexibility for high-performance applications.
Industry Applications
Our GH4169 tubes are a staple in aerospace, powering critical jet engine parts like turbine blades, discs, and combustors that face intense heat and stress. Its high strength and corrosion resistance make it ideal for these applications, ensuring long-lasting performance. Beyond aerospace, GH4169 is used in power generation for gas turbines, in petrochemical plants for high-temperature pipelines, and in nuclear reactors for components needing extreme durability. It’s also perfect for additive manufacturing, enabling complex, lightweight parts for next-gen designs.
