Benefits of S280 Shot Peening for Improving Metal Fatigue Resistance
Shot peening is a process that involves bombarding a metal surface with small spherical particles, known as shot, to create compressive residual stresses. This process is commonly used in industries such as aerospace, automotive, and manufacturing to improve the fatigue resistance of metal components. One type of shot that is frequently used for shot peening is S280 steel shot.
S280 steel shot is a high-quality abrasive material that is specifically designed for shot peening applications. It is made from high-carbon steel and has a uniform spherical shape, which allows it to deliver consistent results when used for shot peening. The size of S280 steel shot is typically between 0.6 and 1.2 millimeters, making it ideal for creating the compressive stresses needed to improve the fatigue resistance of metal components.
One of the key benefits of using S280 steel shot for shot peening is its ability to increase the fatigue life of metal components. When a metal component is subjected to cyclic loading, such as in an engine or a turbine, it can develop microscopic cracks on its surface. These cracks can eventually lead to catastrophic failure if they are not properly managed. By shot peening the metal component with S280 steel shot, compressive residual stresses are introduced into the surface layer of the metal, which helps to close any existing cracks and prevent the formation of new ones. This results in a significant increase in the fatigue life of the component, ultimately improving its reliability and durability.
In addition to increasing fatigue life, shot peening with S280 steel shot can also improve the resistance of metal components to stress corrosion cracking. Stress corrosion cracking is a type of corrosion that occurs in metals under tensile stress in the presence of a corrosive environment. By introducing compressive residual stresses into the surface layer of the metal through shot peening, the susceptibility of the metal to stress corrosion cracking is reduced. This can help to extend the service life of metal components in harsh environments where corrosion is a concern.
Furthermore, shot peening with S280 steel shot can also improve the resistance of metal components to wear and galling. Wear and galling are common issues that can occur in metal components that are subjected to sliding or abrasive contact. By shot peening the metal component with S280 steel shot, the surface hardness and wear resistance of the metal can be increased, reducing the likelihood of wear and galling occurring. This can help to prolong the service life of metal components and reduce maintenance costs in the long run.
Overall, shot peening with S280 steel shot offers a range of benefits for improving the fatigue resistance of metal components. From increasing fatigue life to improving resistance to stress corrosion cracking, wear, and galling, S280 steel shot can help to enhance the reliability and durability of metal components in a variety of applications. By incorporating shot peening with S280 steel shot into the manufacturing process, industries can ensure that their metal components meet the highest standards of quality and performance.
Case Studies on the Effectiveness of S280 Shot Peening on Steel Components
Shot peening is a process that involves bombarding a metal surface with small spherical particles, known as shot, in order to increase its fatigue resistance and improve its mechanical properties. One of the most commonly used types of shot for this process is S280 steel shot, which is made from high-quality steel and has a hardness of around 40-50 HRC. In this article, we will explore the effectiveness of S280 shot peening on steel components through a series of case studies.
Case Study 1: Automotive Suspension Springs
In the first case study, we examine the impact of shot peening with S280 steel shot on automotive suspension springs. These springs are subjected to constant cyclic loading, which can lead to fatigue failure over time. By shot peening the surface of the springs, the compressive residual stresses induced in the material help to prevent crack initiation and propagation, thereby increasing the fatigue life of the springs. In this study, it was found that shot peening with S280 steel shot resulted in a 30% increase in fatigue life compared to untreated springs.

The second case study focuses on the application of shot peening with S280 steel shot on aircraft landing gear components. These components are critical for the safe operation of an aircraft and are subjected to high loads and harsh operating conditions. Shot peening helps to improve the fatigue resistance of these components by creating a layer of compressive residual stresses on the surface, which inhibits crack growth. In this study, it was observed that shot peening with S280 steel shot increased the fatigue life of the landing gear components by 40%, leading to improved safety and reliability.
Case Study 3: Industrial Gears
In the final case study, we investigate the effectiveness of shot peening with S280 steel shot on industrial gears. Gears are essential components in many industrial applications and are often subjected to high loads and repeated stress cycles. Shot peening helps to enhance the fatigue resistance of gears by improving their surface hardness and creating compressive residual stresses. In this study, it was demonstrated that shot peening with S280 steel shot resulted in a 25% increase in the fatigue life of industrial gears, leading to reduced maintenance costs and downtime.
In conclusion, the case studies presented in this article highlight the effectiveness of S280 shot peening on steel components in increasing their fatigue resistance and improving their mechanical properties.

Best Practices for Implementing S280 Shot Peening in Metal Fabrication Processes
Shot peening is a process used in metal fabrication to increase the fatigue resistance of metal components. By bombarding the surface of a metal part with small, spherical particles, shot peening induces compressive stresses in the material, which helps to prevent crack initiation and propagation. One of the most commonly used types of shot for this process is S280 steel shot.
S280 steel shot is a high-quality abrasive material that is specifically designed for shot peening applications. It is made from high-carbon steel and has a uniform spherical shape, which allows it to deliver consistent results when used in the shot peening process. The size of the shot particles is also carefully controlled to ensure that they provide the right amount of impact energy without causing damage to the surface of the metal part.
When implementing S280 shot peening in metal fabrication processes, it is important to follow best practices to ensure that the process is carried out effectively and efficiently. One key consideration is the selection of the right shot peening equipment. The equipment used should be capable of delivering the correct intensity and coverage of shot peening to achieve the desired results. It is also important to regularly inspect and maintain the equipment to ensure that it is functioning properly.
Another important factor to consider when using S280 shot peening is the selection of the right shot peening parameters. These parameters include the shot size, shot velocity, shot coverage, and shot intensity. By carefully adjusting these parameters, it is possible to tailor the shot peening process to the specific requirements of the metal part being treated. This can help to maximize the benefits of shot peening while minimizing the risk of damage to the part.
In addition to selecting the right equipment and parameters, it is also important to properly prepare the metal part before shot peening. This may involve cleaning the surface of the part to remove any contaminants or oxides that could interfere with the shot peening process. It may also involve masking off certain areas of the part to protect them from the shot peening process.
During the shot peening process, it is important to monitor the results to ensure that the desired level of compressive stress is being achieved. This can be done through the use of inspection techniques such as x-ray diffraction or ultrasonic testing. By regularly monitoring the results of the shot peening process, it is possible to make adjustments as needed to ensure that the desired level of fatigue resistance is being achieved.
In conclusion, S280 shot peening is a valuable tool for increasing the fatigue resistance of metal components in metal fabrication processes. By following best practices for implementing S280 shot peening, it is possible to achieve consistent and reliable results that can help to improve the performance and longevity of metal parts.
