Spring Material: Inconel
High Temperature & Corrosion Resistant Nickel Alloy
Inconel is a group of alloys containing mostly nickel with chromium and is resistant to corrosion and high temperatures. It was developed in the mid-1900s for nuclear reactor applications.
Grades / Attributes
Inconel X-750 is most common for spring and wire because this grade offers the best combination of high temperature, corrosion resistance, and availability. Inconel 718 and 600 are also used for coiled springs as well as Belleville washers.
Valves that are used with high temperature fluid or steam (nuclear reactors for submarines and aircraft carriers). An example is the springs used in vacuum furnaces for semiconductor manufacturing. It is also National Association of Corrosion Engineers (NACE) approved for “down hole” gas exposure. Other uses include lower-tier tools, which will not be subjected to severe service or have a short lifespan, where term corrosion exposure is not an issue.
Moderate resistance to chlorides, saltwater and acids. If your application requires more strength and corrosion resistance, upgrade to MP35N or Elgiloy.
