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, environment resistance, and fabricability of any commercial nickel-base alloy.
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.
230® alloy is covered by ASME Section VIII, Division I, and ASME Section I, Code Case 2063, both up to 1650°F (900°C). 230 alloy is also covered by a number of ASTM and AMS specifications.
