Hastelloy C-276 Strip for Chemical Reactor Heat Exchanger Fins
Our Hastelloy C-276 strip is a total game-changer for chemical reactor heat exchanger fins, built to handle the nastiest corrosive environments without breaking a sweat. This nickel-molybdenum-chromium alloy, with about 57% nickel, 16% molybdenum, 16% chromium, plus a touch of tungsten and iron, is our go-to for applications where corrosion resistance and durability are critical. Whether it’s heat exchanger fins, linings, or structural supports in chemical reactors, this strip keeps your systems running smooth and efficient.
What makes Hastelloy C-276 strip stand out is its incredible ability to resist corrosion from tough acids like sulfuric, hydrochloric, and nitric, as well as chlorides and alkalis. It’s perfect for heat exchanger fins in chemical reactors, fighting off pitting, crevice corrosion, and stress corrosion cracking to ensure long-lasting performance with minimal maintenance. This strip keeps your reactors efficient, delivering top-notch heat transfer in the harshest conditions.

This strip’s versatility is a major win. It’s stable up to 1093°C, which is awesome for chemical reactors operating in high-heat environments, like those in petrochemical or pharmaceutical plants. Its low thermal conductivity (~10 W/m·K) is great for precise heat transfer control, and its high strength ensures it holds up under mechanical stress. From fertilizer production to acid manufacturing, Hastelloy C-276 delivers.
We love how adaptable this strip is, even with its complex alloy makeup. You can stamp, bend, or weld it into whatever your fin design needs—think thin, high-efficiency fins or sturdy linings. Need a specific width, thickness, or finish? We can tailor it to fit your specs, ensuring smooth fabrication and keeping your project on track.
