Rene 41

Fact Sheet

Spring Material: Rene 41

Super High Temperature Alloy

Rene 41 is an alloy of nickel, cobalt and chromium, developed for super high temperatures up to 1,500°F.

Grades / Attributes

It frequently is the only spring wire that is suitable for a ceramic application requiring force at 1,500°F. Also valves located in, or next to, a furnace.

Spring Applications

Any spring wire application that is exposed to super-high temperatures, such as refractories.

Material Benefits

Superior performing compared to Inconel alloys.

Considerations

High cost and not good for applications requiring high strength.
