Spring classification

Common springs can be classified into three categories: tension coil springs, compression coil springs, and torsion coil springs
As an important component in industrial systems, springs have a large usage and a wide variety of types, making them commonly used parts in the mechanical industry and daily life. Springs can generate significant elastic deformation under load, converting mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original state, converting deformation energy into mechanical work or kinetic energy
Spring steel wire is a type of steel wire used for making springs or steel wire components. Due to the fact that springs rely on elastic deformation to generate energy, spring steel wires do not necessarily need to have high plasticity, but at least they must have plasticity that can withstand spring forming and enough toughness to withstand impact energy
According to the different uses of springs, there are various types of spring steel wires required for making springs, such as spring steel wires with lower requirements for mattress springs, spring steel wires for shock absorbers, spring steel wires for suspension springs, spring steel wires for engine valves, and spring steel wires for camera shutters. Although there is no unified standard classification name, the quality requirements for these steel wires are different. Springs used in specific environments also have special requirements for steel wires, such as springs used in corrosive media that must have good corrosion resistance. The spring used in accurate instruments should have long-term stability and sensitivity, low temperature coefficient, high quality factor, small aftereffect, and constant elastic modulus. Springs working under high temperature conditions are required to maintain sufficient elastic limit and good creep resistance even at high temperatures
