SPRING STEEL WIRE

Spring steel wire is a kind of steel wire used to make springs (SPRING) or wire forms (WIRE FORM). According to the different uses of springs, there are many types of spring steel wires required for making springs, such as spring steel wires for mattress springs (referred to as mattress steel wires), 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, etc. Although there is no unified standard classification name, the quality requirements of these steel wires are different. Spring steel wires can also be classified according to the manufacturing process, such as raw spring steel wires (not quenched in a lead bath before drawing), lead quenched spring steel wires, galvanized spring steel wires, oil quenched spring steel wires, etc.

PRODUCT USE

The spring is used within the elastic range and should return to its original position after unloading. It is hoped that the plastic deformation is as small as possible, so the steel wire should have a high elastic limit, yield strength and tensile strength. The higher the yield strength ratio, the closer the elastic limit is to the tensile strength, so the strength utilization rate can be improved, and the spring elasticity made is stronger.

Springs absorb impact energy through elastic deformation, so spring wire does not necessarily have to have high plasticity, but at least it must have plasticity that can withstand spring forming and sufficient toughness to withstand impact energy.

Springs usually work for a long time under alternating stress, so they must have a high fatigue limit and good anti-creep and anti-relaxation properties.
