How long can the spring last?

How long can stainless steel springs last? This is a common problem. You might think that as long as it’s not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as “spring”. Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors.

1. Spring design

Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you’re not sure, experts can help guide your decision.

2. Quality of manufacturing materials

The life of the spring is also related to the quality and modulus of elasticity of the materials used in its manufacture. Make sure your springs are made of the best quality material for the desired application. For example, stainless steel springs have high strength, low stress relaxation, corrosion resistance and heat resistance. However, their performance decreases at sub-zero temperatures.

3. Application pressure and environmental conditions

If the force applied is greater than the spring is designed to withstand, fracture may occur. If extension springs are too long, they can suffer irreparable damage. Longer life can be expected if you keep the deflection of the oil tempered spring within a maximum of 25% of its overall length.

A practical example of the scroll spring, considering the product design of the dog walker, Qianye Precision uses high-precision, high-hardness 301 stainless steel for the scroll spring used in the dog walker, and its thickness tolerance is controlled within the range of 0.01mm , Its hardness is HV580 degrees, and the service life of the dog walker can be extended to 30,000 to 100,000 times. This kind of scroll spring is applied to the dog walker, and the quality of the dog walker has been greatly improved. Qianye Precision Spring Engineers can help you get the most out of your springs.
