3 inch compression spring
With springs the elastic limit is the maximum amount of stress or pressure the material/spring can hold until it deforms.
Elastic Limit with Springs
If a spring has way too much pressure on it, and it breaks, or the coils permanently loosen. The coiling spring will reach its maximum elastic limit and it will be deformed until it’s fixed.
Compression springs that are cheap can reach their elastic limit often. Coiling Technologies offers very strong springs that have a high elastic limit.
