Precautions For The Selection Of Spring Materials

A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc.

The choice of spring material should be determined according to the nature of the spring's load, stress state, stress level, working temperature, environmental medium, service life, requirements for electrical conductivity, process performance, material source and price.

When determining the shape and size of the material section, the series of sizes specified in the national standards and ministerial standards should be preferred, and materials with non-standard series specifications should be avoided as much as possible.

Medium and small springs, especially helical tension springs, should preferably use reinforced steel wires, lead bath isothermal cold drawn steel wires and oil quenched and tempered steel wires, which have high strength and good surface quality, and their fatigue performance is higher than that of ordinary quenching. Tempered steel wire, simple processing, good manufacturability and stable quality.
