stainless compression springs

This can be a tough question to answer since springs are used in such a diverse range of products and assemblies. Spring life expectancy is sometimes unpredictable due to the many variables that influence spring performance, including materials used, environmental conditions, and the amount of force involved in the application. Spring design also affects how long the spring will last. In fact, most cases of shorter than expected spring life occur due to a problem with the design of the spring.

Spring Life Expectancy

Spring design flaws that effect life expectancy can involve poor materials and workmanship, but they can also be due to improper design. If a spring was not designed properly for its function, you can expect the spring life to be very short. Stress or force beyond what the design allows can cause the spring to break or cause it to set. For example, an extension spring designed for strength may lack flexibility. If extended too far, it may break in the body or at the ends.

Choosing the right material for the application is another critical part of the design. Hard drawn wire is most often used for low stress applications, while high stress applications need a stronger choice, such as music wire. If the spring will be exposed to harsh elements, consider using a grade of stainless steel or zinc plating. These options will deter rust and improve the spring’s life expectancy.
