What are the Failures of Springs?

Share this blog:

Springs are integral components in various industries, playing a crucial role in the functionality and performance of machines and equipment. However, over time, springs can experience failures that can have detrimental effects on the systems they are a part of. In this article, we will explore the common failures of springs, delve into their causes, and provide potential solutions to address these issues.

1. Fatigue Failure

One of the most prevalent failures of springs is fatigue failure. This occurs when a spring is subjected to repeated or cyclic loading over an extended period, resulting in the weakening and development of cracks within the material, ultimately leading to failure.


  • Overloading: Applying excessive force or load beyond the spring’s design limits can accelerate fatigue failure. This can happen due to poor load calculation or unexpected external forces that surpass the spring’s load-bearing capacity.
  • Insufficient material strength: Springs made of low-quality materials or those that have undergone improper heat treatment can significantly reduce their fatigue life. It is crucial to select materials with appropriate strength and fatigue resistance properties.
  • Improper design: Inadequate considerations for stress distribution or improper spring dimensions can contribute to fatigue failure. It is essential to design the spring with proper stress distribution and suitable dimensions specific to the application requirements.


  • Material selection: Choosing high-quality materials with appropriate strength and fatigue resistance properties can enhance the durability and longevity of the spring. Materials like alloy steels or stainless steels are often preferred for their excellent fatigue resistance.
  • Proper design: Ensuring the spring is designed with proper stress distribution and suitable dimensions according to the specific application requirements is crucial. This involves considering factors such as stress concentration, spring rate, and wire diameter, among others.
  • Regular inspections: Periodic assessments can identify signs of fatigue, such as cracks or deformations, allowing for timely replacement or repair. These inspections can be carried out using non-destructive testing techniques like visual inspection, magnetic particle inspection, or ultrasonic testing.

2. Corrosion

Corrosion is another significant cause of spring failure, especially in environments with high humidity or exposure to corrosive substances. When springs corrode, their structural integrity is compromised, resulting in reduced performance and potential breakage.


  • Moisture and humidity: Springs exposed to excessive moisture or high humidity levels are prone to corrosion. The presence of water or moisture acts as a catalyst for the corrosion process.
  • Chemical exposure: Contact with corrosive chemicals or substances can accelerate the corrosion process. These chemicals can react with the spring material, leading to the degradation of its surface and eventual failure.
  • Lack of protective coating: Springs without proper protective coatings are more susceptible to corrosion. The absence of a protective barrier leaves the spring vulnerable to the corrosive elements present in the environment.


  • Protective coatings: Applying appropriate protective coatings can significantly enhance a spring’s resistance to corrosion. Coatings such as zinc plating or powder coating create a physical barrier between the spring material and the corrosive environment, preventing direct contact and minimizing the risk of corrosion.
  • Material selection: Choosing materials with inherent corrosion resistance properties is crucial in mitigating the risk of corrosion. Stainless steel and specific alloys like Inconel or Monel are commonly used for their excellent corrosion resistance in challenging environments.
  • Regular maintenance: Regular cleaning and inspections can help identify and address any signs of corrosion before they cause significant damage. This includes removing any accumulated dirt, debris, or corrosive substances from the spring’s surface and ensuring proper lubrication.

3. Wear and Tear

Springs are subject to wear and tear over time, especially when constantly in use. This gradual deterioration can lead to reduced spring performance, decreased load-bearing capacity, and eventual failure.


  • Friction: Continuous movement and friction between a spring and other components can result in wear and tear. This is particularly true in applications where the spring is under constant stress or subjected to repetitive motion.
  • Lack of lubrication: Insufficient or improper lubrication can increase friction and accelerate wear and tear. Inadequate lubrication reduces the ability of the spring to absorb and distribute forces effectively, leading to premature failure.
  • Contamination: Dust, debris, or foreign particles in the surrounding environment can contribute to wear and tear. These particles can act as abrasives, accelerating the deterioration of the spring surface and compromising its functionality.


  • Lubrication: Applying suitable lubricants can reduce friction and minimize wear and tear. Proper lubrication creates a protective film between the spring and other components, reducing the direct contact and minimizing the effects of friction.
  • Regular cleaning: Removing dust, debris, and other contaminants from the spring’s vicinity can help maintain optimal performance. Regular cleaning prevents the accumulation of abrasive particles that can cause wear and tear.
  • Periodic inspection: Regular checks can identify any signs of wear and tear, allowing for timely maintenance or replacement. These inspections can involve examining the spring’s surface, checking for signs of corrosion, cracks, or deformations.

4. Overloading

Subjecting a spring to excessive force or overload beyond its design limits can cause immediate failure or significantly shorten its lifespan.


  • Improper installation: Incorrectly installed springs or using the wrong type of springs for the application can lead to overloading. It is crucial to ensure proper installation techniques and the use of appropriate tools to prevent overloading caused by installation errors.
  • Lack of load calculation: Insufficient consideration of the anticipated load requirements can result in overloading. Proper load calculations based on the application’s needs are essential to determine the correct spring specifications.
  • Unforeseen external forces: Sudden impacts, vibrations, or unexpected forces can exceed the spring’s load-bearing capacity. These external forces may be beyond the spring’s design limits and can lead to immediate failure.


  • Proper installation: Ensuring correct installation techniques and using appropriate tools can prevent overloading caused by installation errors. This includes following manufacturer guidelines and using proper fasteners or brackets to secure the spring in place effectively.
  • Load calculations: Conducting thorough load calculations based on the anticipated requirements can help determine the correct spring specifications. This involves considering factors such as the maximum expected load, the spring’s deflection requirements, and the safety factor.
  • Reinforcement or redesign: If overloading is a recurrent issue, reinforcing the spring or considering a redesign with stronger materials may be necessary. Reinforcement techniques like adding support structures or using thicker wire can help enhance the spring’s load-bearing capacity.


Understanding the common failures of springs is essential for preventing performance issues, machinery breakdowns, and potential safety hazards. By addressing factors like fatigue failure, corrosion, wear and tear, and overloading, we can enhance the longevity and reliability of springs in various applications. Regular maintenance, appropriate material selection, and proper design considerations can significantly reduce the risk of spring failures, ensuring smooth and efficient operation in industrial systems.
