0.10mm-25.0mm Flexible Music Spring Steel Wire Suppliers Sheet Die Wire Coil Spring

When ordering steel wire, select the appropriate steel wire standard from Table 1 according to the application.
The mechanical spring is recommended to adopt the ISO8458-2 standard (lead-hardened steel wire). The lead-quenched steel wire has a very fine pearlite structure and good fatigue properties.
Non-mechanical springs can be made of raw drawn steel wire (no lead quenching treatment before drawing), YB/T is recommended
5220-93 or JISG3521 standard, can be used for furniture, car seat cushions, interior decoration, static load springs with low stress, and can also be used to strengthen plastic pipes, screens and tools.
Choosing raw drawn steel wire as mechanical spring may cause problems such as insufficient fatigue life.

Spring steel alloys feature the unique characteristic of being able to withstand considerable twisting or bending forces without any distortion. Products made from these steel alloys can be bent, compressed, extended, or twisted continuously, and they will return to their original shape without suffering any deformation. This characteristic is defined as high yield strength and is the result of the specific composition and hardening of the steel alloy. Spring steels are medium-to-high carbon content alloys generally featuring a carbon content of 0.5 to 1.0 percent.

Application:mattress spring, compression spring, extension spring, torsion spring , mechanical spring, wire forms, core of controlling cable, connecting wire, hard needle.
