What will happen if you use a stretch spring for a long time? Long-term application, will make the shape of the spring and its characteristics vary greatly, if always in a certain type of situation, stretch spring manufacturers will be due to external standards and produce qualitative change, usually have the following conditions:

1, stretch spring wear: wear is divided into, abrasive, fatigue and corrosion wear fracture.

2. Etch fatigue fracture: the tensile spring is broken under the combined action of cyclic load cutting and corrosive medium.

3. Stress corrosion rupture: tensile spring rupture is caused by the mutual effect of tensile stress and corrosive medium.

4, brittle fracture: most of the spring fracture belongs to the brittle fracture, only when the working temperature is high, there will be plastic fracture, in the engineering fatigue fracture, stress corrosion fracture and cyanide brittle fracture known as brittle fracture.

5, cyanide crisp, cadmium crisp, black crisp: because the spring material impurities in the water content is too high resulting in brittle.

6. Tensile spring fatigue rupture the spring rupture under cyclic load.
