nickel super alloy is an ideal material for applications that need to withstand extreme temperatures. It offers excellent resistance to corrosion and oxidation at high temperatures and is an extremely popular choice across a wide range of industries.
Inconel is the most commonly used of the nickel-based superalloys and is highly resistant to oxidation and corrosion in a variety of environments. It is often welded to other materials to form components for a range of different industries including aerospace, chemical processing and oil & gas.
The most common machining method for nickel super alloys is to use cobalt drills. This is especially useful when using twist drill bits and can be particularly beneficial in certain areas, such as the ejector pins on gas turbine components.
CNC machining is also a great option, and a range of tooling options can be used to ensure the best possible results. It is particularly important to ensure that you choose the correct type of insert, which can make or break the machining process.
During the machining process, it is important to monitor the quality of the alloy and the microstructure within each part. This will help to determine whether it will perform well or if there are any issues that need to be addressed.
Another important aspect is the grain size. Large un-recrystallized grains (URGs) can significantly impact both the strength and stress rupture properties of the material. This is why it is crucial to get a fully recrystallized microstructure and fine, uniform grain size in order to achieve the desired performance.
