Some terminologies of spring steel wire

"Prestress of spring steel wire? What dose it mean? Low-relaxation? What exactly is this? Patenting? Oh, I don't specifically." Maybe you will meet this kind of confusions when you're choosing the steel wire, well then, i'll give you an introduction about these terminologies of spring steel wire, for you to choose the steel wire simply.

• Prestress.

Prestress is usually to offset the spring steel wire's stress suffered during its service as well as improve the load bearing capacity by some technical means. This is a long-term reverse stress put on the spring steel wire before its service. Prestress is not merely used in spring steel wire, in addition, it used in bridge, telegraph pole etc.

• Low-relaxation

When the spring steel wire is keeping the tensile stress, the load will gradually descend. This phenomenon is stress relaxation. The proportion with the loss relative to the initial stress of spring steel wire is a stress relaxation rate. By way of the special process, we can help characteristics and achieve a lesser relaxation rate, which is the basic specification of the concept of low-relaxation

• Patenting

Patenting technology widely used by way of the global spring steel wire industry, it's really a heat treatment technology to make the high-quality steel wire. The spring steel wire of patenting has a more fatigue resistance versus spring steel wire drawn directly by rod, plus the performance and toughness with the final product are better.

Besides, there are additional spring steel wire's terminologies. After you have a shorter understand of them, the knowledge may play an important role in purchasing the spring steel wire.
