Tensile spring manufacturers introduced the corrosion of the spring, from the reaction type is divided into chemical corrosion and electrochemical corrosion. This is a change in the principle of the surface metal, or gain and loss of electrons. How to avoid chemical corrosion? This requires care not to form water films or droplets on the surface of the stretch spring in humid environments, especially in the atmosphere. At this point, it is easily soluble in electrolytes, and is easily corroded by electrolysis.
Electrochemical corrosion is the main cause of corrosion found by tensile spring manufacturers. But at the same time, these two kinds of corrosion often occur at the same time, may be the corrosion of the surrounding media. Stretch spring in the process of use, once corrosion occurs, its elasticity will gradually lose, so must do a good job of protection, so that stretch spring can play a good role.
The choice of material of stretch spring manufacturers should be determined according to the nature of the spring load, stress state, stress size, working temperature, environmental media, service life, the requirement of conductive and magnetic conductivity, process performance, material source and price.
Carbon spring steel wire and piano steel wire have large residual stress after cold drawing, and there is large residual stress after processing stretch spring, and the size changes greatly after tempering, so it is difficult to control the size accuracy. Oil quenching and tempering steel wire is modulated and strengthened after the steel wire is drawn to the specified size, basically there is no residual stress. After forming the stretch spring, it is tempered at low temperature, the size changes very little, and the heat-resistant stability is better than cold-drawn strengthened steel wire.
Spiral spring material section, should be the first choice of circular section. Square and rectangular cross-section materials, strong bearing capacity, good impact resistance, and can make the spring miniaturization, but less material sources. And the price is higher, except for special needs, generally try not to choose this material. In recent years, the circular steel wire was developed to replace trapezoidal steel wire with flat steel wire, and good results were obtained.
