High Carbon Spring Steel Wires for Manufacturing Springs

High carbon spring steel wire is cold drawn from non-alloy high carbon steel, and it is mainly used for manufacturing springs and other wire forms. Because of the high carbon content and precision cold drawn process, the produced springs have high elasticity and low deformability, so they can sustain frequently repeated high pressure when they are applied to automobile industry or numerical control machine tools.

Highlights of springs made of our high carbon spring steel wires:

  • High corrosion resistance after galvanized.
  • High tensile strength.
  • Good toughness.
  • Strong stress resistance.
  • High ductility.
  • Low deformability.
  • Small tolerance.

Applications:
High carbon spring steel wires can be used to produce springs with extremely high tensile strength and ductility. These springs are mainly used in automobile industry, CNC machine tools and furniture. Besides springs, high carbon spring steel wires can also be used in the manufacture of high carbon steel ropes and mining mesh.
