Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting.

Grades
Many grades of steel can be hardened and tempered to suit application as a spring; however, some steels exhibit more desirable characteristics for spring applications.

Applications
- Applications include piano wire (also known as music wire) such as ASTM A228 (0.80-0.95% carbon), spring clamps, antennas, springs, and vehicle coil springs, leaf springs, and s-tines.
- Spring steel is also commonly used in the manufacture of metal swords for stage combat due to its resistance to bending, snapping or shattering.
- Spring steel is one of the most popular materials used in the fabrication of lockpicks due to its pliability and resilience.
- Tubular spring steel is used in the landing gear of some small aircraft due to its ability to absorb the impact of landing.
- It is also commonly used in the making of knives, especially for the Nepalese kukri.
- It is used in binder clips.
