If you are looking for a high temperature, corrosion resistant alloy, consider Haynes 230 or Inconel 718. Both nickel-based alloys offer exceptional strength and resistance to oxidation at extreme temperatures, but there are some key differences between the two that make them better suited for different applications.
Differences in chemical composition:
The main difference between Haynes 230 and Inconel 718 is their composition. Inconel 718 contains chromium, niobium, iron and molybdenum in addition to nickel. The presence of these additional elements allows it to maintain strength at higher temperatures than Haynes 230 while also providing better corrosion resistance. The disadvantage is that it is more expensive to produce than the Haynes 230 due to the additional components required.
Haynes 230, on the other hand, is primarily composed of nickel, with small amounts of cobalt and chromium added for improved corrosion resistance. While Haynes 230 is not as strong as Inconel 718 at higher temperatures, it is much less expensive due to its simpler composition. This makes it an excellent choice for applications that do not require the same performance levels as Inconel 718 but still require superior heat resistance and corrosion protection.
What each alloy is used for:
In general, Inconel 718 is best suited for applications involving high temperatures, such as jet engines or gas turbines. Its combination of strength and corrosion resistance makes it ideal for these applications, as it can withstand the heat generated by these machines as well as any corrosive elements they may encounter in their environment. In addition, its relatively low coefficient of thermal expansion makes it suitable for use in parts that require precision machining, such as gears and bearings. Haynes 230, on the other hand, is better suited for less demanding applications such as exhaust systems or furnace components because it is lower cost and has good temperature performance up to 1000°F (538°C). It is also used in medical implants as its cobalt content helps provide superior wear resistance over other alloys such as stainless steel or titanium.
in conclusion:
When choosing between Haynes 230 and Inconel 718 alloys, carefully consider the unique needs of your application before making your decision. While both alloys offer excellent strength and excellent corrosion resistance at high temperatures, their compositions make them better suited for different uses based on your specific requirements. If you need an alloy with superior strength at high temperatures, then Inconel 718 is probably the best choice; however, if cost is a significant issue, consider Haynes 230 – it offers plenty of performance at a fraction of the price!
