Material Type: Hard Drawn
Material Group: Carbon Steel Wire
Hard drawn springs are manufactured from economical cold drawn carbon steel wire designed for standard, average stress applications. Known as a cost-effective and dependable material option, hard drawn spring wire provides consistent performance for general purpose springs, commercial hardware, and custom wire forms that do not require fatigue resistance or high-precision deflections.
Spring Engineers designs and manufactures custom hard drawn springs including compression springs, extension springs, torsion springs, and wire forms.
