Carbon Spring Steel Wire is usually made of 65#, 70#, 65Mn, 82B and other materials. It has low plasticity, strong elasticity and excellent stress resistance. After special processing, it has a high elastic limit and yield strength, and can withstand high-intensity pressure and tension. The wire diameter is usually φ0.20mm - φ6.50mm, and is widely used in the automotive, machinery manufacturing, stationery and power tools industries to manufacture various springs and elastic components.
Typical applications
Automotive industry
suspension springs, clutch springs, valve springs
Machinery manufacturing
stamping die springs, shock absorber springs
Household appliance hardware
battery contacts, switch springs, toy springs
Daily necessities
furniture springs, stationery clips, fishing tackle
Production Process
• Wire rod selection: Select high carbon steel wire rods to control the uniformity of composition.
• Cold drawing: Multiple drawing passes to gradually reduce the diameter and increase the strength.
• Heat treatment: Lead quenching or oil quenching to optimize the metallographic structure.
• Surface treatment: Phosphating, galvanizing or oiling for rust prevention.
• Testing and dividing the rolls: Test the mechanical properties to ensure dimensional accuracy.
