Different choices of various spring materials

(Summary description)The choice of spring material shall be determined according to the nature of the spring bearing load, stress state, stress magnitude, operating temperature, environmental medium, service life, requirements for conductive magnetic permeability, process performance, material source and price.

The choice of spring material shall be determined according to the nature of the spring bearing load, stress state, stress magnitude, operating temperature, environmental medium, service life, requirements for conductive magnetic permeability, process performance, material source and price.

 

In determining the cross-sectional shape and size of the material, the series sizes specified in the national standards and ministerial standards should be preferred, and materials of non-standard series specifications should be avoided as much as possible.

 

Medium and small springs, especially spiral tension springs, should be preferentially treated with reinforced steel wire, lead bath isothermal cold drawn steel wire and oil quenched tempered steel wire, with high strength and good surface quality, fatigue performance is higher than ordinary quenching The tempered steel wire is simple in processing, good in processability and stable in quality.

 

After the carbon spring steel wire and the piano wire are cold drawn, a large residual stress is generated. After the spring is processed, there is a large residual stress, and the dimensional change after tempering is large, and it is difficult to control the dimensional accuracy. Oil quenching and tempering steel wire is made by modulating and strengthening the steel wire after the steel wire is drawn to the specified size. Basically, there is no residual stress. After forming the spring, it is tempered at low temperature, the dimensional change is small, and the heat resistance stability is better than cold drawing. Strengthen the steel wire.

 

For large and medium-sized springs, cold-drawn or cold-drawn polished steel should be used for load accuracy and stress. For springs with low load accuracy and low stress, hot rolled steel is available.

 

The leaf spring is generally selected from flat steels such as 55Si2Mn, 60Si2MnA, 55SiMnVB, 55SiMnMoV, 60CrMn, and 60CrMnB.

 

For the material section of the coil spring, a circular section should be preferred. The square and rectangular cross-section materials have strong bearing capacity and good impact resistance, and the spring can be miniaturized, but the material source is small. And the price is higher, except for special needs, generally try not to use this material. In recent years, the development of round steel wire flattening instead of trapezoidal steel wire has achieved good results.
