Types of stretch spring materials

Tension springs refer to springs that can work in electronics and are resistant to corrosion by weakly corrosive media such as air, steam, water, and chemically corrosive media such as acids, alkali, and salts. Many working environments such as chemical machinery and electronics require corrosion resistance and resistance to corrosion. A medium-temperature, non-magnetic elastic component. The Tension Spring can produce large elastic deformation when loaded, converting mechanical work or kinetic energy into elastic potential energy. After unloading, the deformation of the tension spring disappears and returns to its original state, reducing the deformation. Energy can be converted into mechanical work or kinetic energy.

Tension springs should have excellent overall properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), anti elasticity loss function (i.e. anti-elasticity loss function, also known as anti-relaxation function), fatigue performance, and hardenability. , physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above functional requirements, spring steel has excellent metallurgical quality (high purity and uniformity), excellent surface quality (strict control of surface defects and decarburization), precise shape and size.

Generally, cylindrical springs are the most widely used because they are simple to make, can be made into various types according to the load conditions, and have a simple structure. Generally speaking, springs should have high elastic limit, fatigue limit, impact toughness and excellent heat resistance and corrosion resistance. Commonly used materials are listed above. Commonly used spring wires with a diameter of less than 20 mm are cold rolled. After the tension spring is made, it must be pressed or polished to improve the load-bearing capacity and surface finish of the Wire forming.
