What is the importance of steel in helical spring (i want clearly)?

Question

suggest the use fullness of steel as material in helical springs based on design and require ments of helical spring (i want details with clearly )

Answer 1

*A Coil spring, also known as a helical spring, is a mechanical device, which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded.

Coil springs are a special type of torsion spring, the material of the spring acts in torsion when the spring is compressed or extended.

The two usual types of coil spring are:

1.Tension coil springs which are designed to resist stretching. They usually have a hook or eye form at each end for attachment.

2.Compression coil springs are designed to resist being compressed. A typical use for compression coil springs is in car suspension systems.

*An ideal spring material has high strength properties, a high elastic limit and a low modulus. Because springs are resilient structures designed to undergo large deflections, spring materials must have properties of extensive elastic range. Other factors such as fatigue strength, cost, availability, formability, corrosion resistance, magnetic permeability and electrical conductivity can also be important properties and must be considered in light of cost/benefit. Consequently, careful selections must be made to obtain the best compromise.

Answer 2

it is mailable, durable, cheap and elastic.

Mailable:  Can be easly shaped then retains that shape

Durable:  Below it's elastic limit it can be flexed millions of times without failing

Cheap: Low cost to manufacture

Elastic:  It can be flexed with almost 100% of the energy IN = energy OUT
