What Factors Affect the Service Life of the Spring?

The spring has the characteristics of being stretchable and compressible, and it is a mechanical part that uses elasticity to work.

Although the spring is a small component, its role can not be underestimated. It plays an important role in many industries such as automobiles, agriculture, electricity, construction, and furniture.


The factors that affect the service life of the spring

In normal use, it will not break as long as it is within the elastic limit. So, what are the factors that affect the service life of the spring?
Here are some of the most common factors:

1. Spring Material

The materials used to make the spring are carbon steel, stainless steel, and some special materials, such as pure copper, rubber, etc. Spring deformation under the action of external force, remove the external force and then restore to the original state. Springs made of different materials have different stress conditions. The life span is necessarily different.

2. Using Environment

Using environment mainly refers to the medium in which it is used, such as water, air, or highly corrosive liquids. Springs are widely used in all walks of life, and there is no doubt that they will face some force majeure factors, such as corrosion. If it works in a corrosive environment, the service life will be significantly reduced. If it uses stainless steel to work in such a high-pressure and high-pressure environment, the springs are easy to break.
Therefore, the application environment of the spring should be considered when selecting materials, and surface treatments such as phosphating, galvanizing, etc. are also required when necessary.

3. Tempering Treatment

Tempering treatment is an indispensable process for manufacturers in the production of springs, which is beneficial to strengthen the tensile strength and stabilize the shape of the spring. Irregular operations during the tempering treatment process will cause the quality of the spring to decrease, or directly cause the spring to be unusable.

4. Surface Treatment

The fatigue strength of springs will be affected by corrosion, bumps, surface roughness, etc. Therefore, the corresponding surface treatment can greatly improve the service life of the spring.

5. Reasonable usage

It mainly refers to the rationality of spring assembly,  working frequency, and working stroke. The fatigue fracture of the spring may occur under such unreasonable conditions, thereby affecting the use of the spring.
