Hastelloy C22 for High-Temperature Aerospace Turbine Seals
Our Hastelloy C22 strip is a total powerhouse for high-temperature aerospace turbine seals, built to handle the extreme heat and corrosive conditions of jet engines and spacecraft systems. This nickel-chromium-molybdenum alloy, with about 56% nickel, 22% chromium, 13% molybdenum, plus a touch of tungsten and iron, is our go-to for applications where corrosion resistance and reliability are critical. Whether it’s seals, gaskets, or structural supports in turbine systems, this strip keeps your aerospace components tight and performing like a champ.
What makes Hastelloy C22 strip stand out is its killer ability to resist oxidation and corrosion at temperatures up to 1038°C. It’s perfect for turbine seals that face intense heat, hot gases, and chemical exposure in high-performance engines. This strip fights off pitting, crevice corrosion, and stress corrosion cracking, ensuring your seals stay leak-free and reliable, even in the toughest aerospace environments.

This strip’s versatility is a huge win. Its high thermal stability makes it ideal for turbine components operating in scorching conditions, like those in gas turbines or rocket propulsion systems. Its low thermal conductivity (~10 W/m·K) helps with precise thermal management, and its high strength ensures it holds up under mechanical stress. From commercial jets to space exploration vehicles, Hastelloy C22 delivers top-notch performance.
We love how workable this strip is, even with its complex alloy makeup. You can stamp, form, or weld it into whatever your seal design needs—think precision gaskets or sturdy supports. Need a specific width, thickness, or finish? We can tailor it to fit your specs, ensuring smooth fabrication and keeping your aerospace project on track.
The aerospace industry’s all about materials that are strong, lightweight, and sustainable, and Hastelloy C22 strip checks every box. It’s recyclable, which is awesome for eco-friendly projects, and its long lifespan means less waste from replacements. With global air travel, defense, and space exploration booming—think next-gen aircraft, urban air mobility, and lunar missions—demand for high-performance materials like Hastelloy C22 is soaring. Its durability supports the trend toward low-maintenance, fuel-efficient aerospace designs.

Our Hastelloy C22 strip sets the standard because we’re all about quality, customization, and customer success. We offer a wide range of widths, thicknesses, and finishes, with fast delivery for both small and large orders. Our team dives into your project, optimizing the strip for your turbine seals to ensure maximum corrosion resistance and performance at high temperatures. We keep pricing competitive, especially for bulk orders, without cutting corners on quality. Our sustainable production process uses recyclable materials, aligning with green aerospace trends. Plus, our hands-on support means you’re always covered—whether it’s technical guidance or a custom solution, we make it happen.
Compared to other materials, our Hastelloy C22 strip is a standout. Hastelloy C276 is great for reducing acids but slightly less effective in oxidizing environments. Stainless steel 17-4 PH is tough but can’t handle high-temperature corrosion like C22. Inconel 718 is strong but less resistant to oxidizing gases at elevated temperatures. Our strip is the go-to for high-temperature aerospace turbine seals.
We craft our Hastelloy C22 strip to meet strict standards like ISO 9001, ensuring quality you can trust every time. Whether you’re building seals for jet engines or supports for spacecraft, this strip’s ready to perform. Got a unique spec in mind? Let us know, and we’ll make it happen.
