WebThe stress is so large that when removed, the material does not spring back to its previous dimension. There is a permanent, irreversible deformation. The minimal value of the stress which produces plastic deformation is known as the elastic limit for the material. WebAs a prediction of the service life, the reference method of JIS B 2704 is shown below. When using wires with excellent fatigue resistance such as piano wire and oil-tempered wire for valve springs, the service life in a normal environment can be estimated by using the fatigue strength diagram in Fig2. σB is the tensile strength of the material.
