Spring steel is a low alloy, medium carbon or high carbon steel with a very high yield strength. This allows products made of spring steel to return to its original shape despite significant bending and twisting.
Most spring steels (as those used in cars) are hardened and tempered to a value of 45 on the C scale of Rockwell.
