We are doing stainless steel spring wire manufacturers can only introduce the point on the stainless steel spring silk elastic knowledge to you.

304 spring wire tensile can do 1100-2300PMA. The higher the resistance, the higher the elasticity. In the case of

When the steel yield to a certain extent, because the internal grain rearrangement of its ability to resist deformation and re-increase, this time although the development of rapid deformation, but only with the increase in stress, until the maximum stress.

Since then, the ability of steel to resist deformation is significantly reduced, and in the weakest place there is a large plastic deformation, where the specimen section quickly shrink, the phenomenon of necking until the fracture damage. The maximum stress value of the steel before the tensile fracture is called the strength limit or the tensile strength.
