Things to consider when choosing a spring for your application:
The selection of material often depends upon the temperature at which the spring will operate. Too hot or too cold and the spring may fail. At colder temperatures, the spring may fracture wherein in hotter temperatures the spring may not return to its original state after compression, extension or torsional stress has been applied.
As tolerances become tighter sometimes an additional cost is incurred because of changes to the setup and operation of the machines to achieve these tolerances. If cost is a major issue then relieving or opening the tolerance requirement could save that little bit extra resulting in an even more competitive price structure.
Unfortunately corrosion is sometimes overlooked when choosing a spring material or finish. Often a corroded area very small in size can lead to spring failure by concentrating stress in one are of the spring. Stainless steels and other alloys can help resolve this problem. In springs that incur high stresses and must be manufactured from a high carbon alloy, a plating may be the answer. Keep in mind when using a plated spring hydrogen embrittlement must be relieved or premature failure may occur. If you have questions in this area, you may want to discuss the application with us prior to choosing a material.
For any given type of application there may be more than one type of spring that can be used. for instance, if you are having problems with the hook fracturing on an extension spring, a compression spring with hooks that run through the body (similar to a storm door safety spring) can be used to reduce fracturing.
Let us know if you are having problems with the spring you are currently using, We may be able to recommend something that works better for the application.
