ISO Series Die Springs - D shape wire - 5 Duty ranges

Special Springs ISO line of die springs conform to ISO 10243. Our die springs are made from Chromium Silicon alloy, high-tensile strength spring steel. Special Springs die springs are coated using Electrophoretic, E-Coat process for an economical, durable finish that is HAPs free, heavy metal free and lead-free. To assure consistent free lengths Special Springs die springs are ground to a tolerance of +/- .5 mm.

Die springs are used primarily in stamping die applications. However, they are also well-suited for many applications where high-static or shock-load stresses are required, or when maximum cycle-life is important. The rectangular wire is employed to reduce the solid height and increase the space efficiency of the design.
