Spring Steel The term yield strength refers to a material’s ability to endure significant bending or twisting and return to its original shape without deforming. Spring steel alloys feature the unique characteristic of being able to withstand considerable twisting or bending forces without any distortion. Products made from these steel alloys can be bent, compressed, extended, or twisted continuously, and they will return to their original shape without suffering any deformation.
