Hastelloy C22 for Oxidation-Resistant Gas Turbine Connectors
Our Hastelloy C22 strip is a total beast for oxidation-resistant gas turbine connectors, built to handle the scorching heat and corrosive gases of aerospace and power generation systems. This nickel-chromium-molybdenum alloy, with about 56% nickel, 22% chromium, 13% molybdenum, plus a dash of tungsten and iron, is our go-to for applications where corrosion resistance and reliability are critical. Whether it’s connectors, fasteners, or structural supports in gas turbines, this strip keeps your systems tight and running smoothly.
What makes Hastelloy C22 strip stand out is its incredible ability to resist oxidation and corrosion from hot gases at temperatures up to 1038°C. It’s perfect for gas turbine connectors that face intense heat, chemical exposure, and mechanical stress in jet engines or power plant turbines. This strip fights off pitting, crevice corrosion, and stress corrosion cracking, ensuring your connectors stay reliable and perform like champs, even in the toughest conditions.
This strip’s versatility is a huge win. Its high thermal stability makes it ideal for turbine components operating in blistering environments, like those in aerospace propulsion or industrial power generation. 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 aircraft to land-based turbines, Hastelloy C22 delivers top-notch performance.
We love how adaptable this strip is, even with its complex alloy makeup. You can form, weld, or stamp it into whatever your connector design needs—think precision fasteners or robust supports. Need a specific width, thickness, or finish? We can tailor it to fit your specs, ensuring smooth fabrication and keeping your project on track.
The gas turbine industry’s all about materials that are strong, durable, 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 demand for efficient air travel and clean energy soaring—think next-gen jet engines and renewable power systems—Hastelloy C22’s oxidation resistance is more critical than ever. Its low maintenance aligns with the trend toward high-efficiency, sustainable turbine designs.
