Best materials in spring manufacturing: a technical article by Transworld Engineering

Continuing its technical article series on spring manufacturing, Transworld Engineering has recently published a new column regarding the most common materials used in spring making. Different compositions provide different properties: hence, choosing the best type of material according to your needs might be key to obtaining the best mechanical characteristics.

Let’s have a look at the most frequently used materials.

Low alloy steel provides several specific benefits over mild steel, making it preferable for particular categories of springs. This type of steel features excellent high-temperature resistance. Therefore, low alloy steel springs resist axial stresses much better.

Cold drawn wire springs, instead, boast better temperature and stress tolerance, as well as improved tensile strength. The drawing process alters the basic crystalline structure of the steel, modifying its mechanical properties.

Oil tempered spring wires are widely used in the automotive field. Multiple classifications define the wire properties in this category, including fatigue stress – the calculation of which is crucial in this industry.

Bainite-hardened steel is the right choice for those who need springs with excellent fatigue resistance and strength.

Stainless steel features incredible yield strength and offers excellent protection against oxidization thanks to its high Chromium content. The Nickel element, instead, provides protection against acids and atmospheric agents. Stainless steel is also extremely resistant to high temperatures.

Copper and titanium alloys are more expensive than usual steel alloys. Therefore, you should choose these materials in specific circumstances where you can justify higher costs. The best examples of such scenarios may include space travel or military aircraft work, where accuracy is crucial.
