Spring steel wire is a type of steel wire used to make springs or wire frames. Depending on the application of the spring, there are various types of spring steel wire required, such as mattress spring wire (for lower-requirement applications), spring steel wire for shock absorbers, spring steel wire for suspension springs, spring steel wire for engine valves, and spring steel wire for camera shutters, etc. Although there is no unified standard classification name, the quality requirements for these wires are different.
Spring steel wire can also be classified according to its manufacturing process, such as raw-drawn spring steel wire (without lead bath hardening before drawing), lead-quenched spring steel wire, galvanized spring steel wire, and oil-quenched spring steel wire.
