Material
Spring steel.
Stainless steel.
Version
Phosphated and oiled.
Note
If several disc springs are assembled to form a spring packet i.e. concave face to convex face, the spring force of a single disc can be multiplied by the number of discs giving high spring force with short spring travel.
If several disc springs are assembled to form a spring column i.e. concave face to concave face and convex face to convex face, the spring force of the entire column is the same as that of a single disc giving low spring force with long spring travel.
