The Benefits of Stainless Steel Springs in Automotive Manufacturing

When selecting metal for coil spring manufacturing, one should carefully consider its ability to perform under stress. A great spring requires high elasticity limits, low plasticity levels and excellent fatigue resistance properties. 301 stainless steel strip is available with all of these properties and comes either in traditional full hard tempers or ultra-high tensile versions with additional silicon for enhanced strength.

Corrosion Resistance

Corrosion resistance is an integral component of spring performance and lifespan, and its influence can vary based on both how much stress they handle as well as environmental conditions in which they operate.

Stainless steel springs are highly corrosion-resistant and can withstand high temperatures without additional protection, making them an excellent choice in environments exposed to corrosive media or chemicals.

Stainless steel cylinder springs are widely utilized by the automotive industry to ensure vehicle safety, providing stiffness, impact absorption, alignment support and fatigue resistance for proper vehicle alignment. Produced in various diameters to meet specific application needs; with grade options tailored specifically for different applications available; springs may even feature deburred edges and be supplied with soap coating to lubricate them during their forming process.


Over time, springs are exposed to tremendous strain. To ensure they can withstand this strain and last as long as possible, durable metals with high elasticity limits and low plasticity as well as high tensile and yield strengths are the optimal choices for making springs.

Stainless steels are widely considered the premier material for making springs. Other alloys, including carbon-based spring alloys and nickel-based spring alloys can also be considered suitable for this task.

Quality springs depend upon their design and the environment in which they will be used. When selecting a material for springs, corrosion, fatigue resistance and environmental considerations must all be considered when making selection decisions. Stainless steels are one of the best-suited choices as they have exceptional corrosion-resistance, formability and can withstand high temperatures as well.


Stainless steel is one of the most versatile materials available to manufacturers, making it an excellent choice for coil spring production. Stainless steel provides strength and stiffness in vehicle components while offering high impact absorption to protect crash safety, and works well in complex forming processes.

Selecting an ideal material for springs is critical as it determines their lifespan. A mistake could cause one or more to fail prematurely and affect its functionality within your device or system.

Manufacturers typically rely on several key metals when crafting springs. Stainless steel springs are made of an iron alloy with at least 11% chromium content. These springs can store energy and can be made into either extension or compression springs for compression applications; their hardness levels can also be customized to meet any particular need in terms of hardness levels for extension applications or compression applications. Finally, heat treating at certain temperatures for an extended time period helps the memory retention.


Stainless steel springs are not only more affordable to produce but are also better for the environment. Since they weigh less, automotive industries can reduce fuel consumption and ultimately decrease pollution levels.

When selectinging spring material for an application, several considerations come into play, including stress/load conditions, corrosion resistance requirements and whether hard or soft springs are needed. Materials used must also have strong fatigue/impact adsorption properties as well as being compatible with complex forming operations.

To protect it from corrosion, springs constructed of stainless steel must either be passedivated or shot peened in order to make them more corrosion-resistant. Passivation involves covering the metal in a solution which removes iron from its surface while shot peening uses small metal “shots” thrown onto it, creating a compressive stress layer and altering its mechanical properties.
