Spring steel is a type of high-carbon alloy steel that is specifically designed for use in the manufacture of springs due to its excellent elasticity and strength. The carbon content in spring steel typically ranges from 0.5% to 0.6% or higher, which contributes to its hardness and the ability to retain its shape under stress. Corrosion resistance spring steel is used in many areas,include: Automotive suspension springs、Torsion springs for doors and gates、Compression springs in various mechanical devices、Clock and watch springs、Springs for mattresses and seating.
