Inconel balls can be made from a variety of Inconel alloys. Inconel alloys are nickel bases with chromium and iron. Many Inconel alloys were developed for specific applications. Inconel balls can be made from these various alloys to satisfy the need for mechanical properties at high temperatures and corrosion resistance to certain chemicals often at elevated temperatures. Inconel alloys generally have excellent creep and rupture strength and high tensile and yield strengths, especially at elevated temperatures. Inconel balls are made for use in jet engine applications where high temperatures exist. Inconel balls and seats have been used by NASA on the space shuttle launch pads. Inconel balls are also made for valves and pumps and other fluid handling equipment when corrosion resistance is required
