Spring steel
Material type: Metal, Magnetic
Spring steel is used 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 sprung steel to return to their original shape despite significant deflection or twisting.

Material advantages
It is usually characterized by a unique property known as high yield strength which refers to a material’s ability to tolerate considerable bending or twisting and return to its original shape without distorting.
Material shortcomings
