When vortex finder tubes and other internals in your cyclone separator aren’t giving you the performance life you need to avoid costly downtime and replacements, turn to HAYNES® 230® alloy for the best in resistance to high-temperature warpage and oxidation damage. 230 alloy is suited for long-term continuous exposure at temperatures as high as 2100°F (1149°C). It is designed to outlast traditional stainless steels, nickel-chromium alloys, and iron-nickel-chromium materials by as much as 10 to 1! And, 230 alloy is both readily fabricable and repairable! Its retention of ductility after being in service for years means you can perform reforming and weld repair operations without any need for pre- or post-repair treatment. So consider HAYNES 230 alloy next time your plant is down for cyclone separator maintenance. It’s the choice that will keep your plant up, and your maintenance costs down.
HAYNES 230 alloy is a top-of-the-line high-performance, industrial heat-resistant alloy for applications demanding high strength as well as resistance to environment. It is a substantial upgrade in performance capabilities from common iron-nickel-chromium and nickel-chromium alloys, and displays the best combination of strength, stability, environmental resistance, and fabricability of any commercial nickel-base alloy. HAYNES 230 alloy can be utilized at temperatures as high as 2100°F (1150°C) for continuous service. Its resistance to oxidation, combustion environments and nitriding, recommends it highly for applications such as nitric acid catalyst grids, high-temperature bellows, industrial furnace fixtures and hardware, strand annealing tubes, thermocouple protection tubes, and many more.
