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.
Any spring wire application that is exposed to super-high temperatures, such as refractories.
Superior performing compared to Inconel alloys.
High cost and not good for applications requiring high strength.
