SPIROL offers a line of austenitic stainless steel Disc Springs in diameters ranging from Ø8mm to Ø71mm. Austenitic stainless steel is typically used for static and low cycle applications that require a heightened level of corrosion resistance. It withstands fresh water and atmospheric marine conditions very well, and is suitable for many other industrial conditions including acidic environments. This material will continue to work harden with use so cycle life is limited, but creep resistance is good.

If you don’t see what you are looking for in our standard offering (including size, quantity, stacks, etc.), please feel free to Request a Quote or contact SPIROL directly for complimentary Application Engineering assistance!

Note: All pricing is based on small box quantities. Please contact SPIROL directly for high volume quotes!
