Specifications and Sizes

Advantages and Benefits

Superior Elasticity & Durability: Our compression springs are engineered for consistent performance under repeated compression cycles. The carefully controlled heat treatment process ensures optimal spring properties, providing reliable force output throughout millions of cycles. The high tensile strength of SS304/SS316 materials guarantees dimensional stability and resistance to permanent deformation.

Exceptional Corrosion Resistance: SS304 stainless steel offers excellent resistance to atmospheric corrosion, water, and many chemicals. For more aggressive environments, SS316 provides enhanced corrosion resistance with its molybdenum content, making it ideal for marine applications, chemical processing equipment, and coastal installations. Both grades maintain their mechanical properties in humid, wet, or chemically exposed conditions.

Extended Service Life: The combination of premium materials, precision manufacturing, and proper surface treatment results in springs that significantly outlast standard carbon steel alternatives. Reduced fatigue failure means fewer replacements, lower maintenance costs, and improved equipment uptime. Our springs are designed for high-cycle applications where reliability is paramount.

Complete Customization: Every parameter can be tailored to your exact requirements – wire diameter, outer diameter, inner diameter, free length, solid height, number of coils, spring rate, and maximum load capacity. Our engineering team works directly with you to optimize spring design for your specific application, ensuring optimal performance and cost efficiency.

Quality Assurance: Manufactured under ISO 9001:2015 quality management system with full material traceability. Each batch undergoes rigorous testing including dimensional inspection, load testing, and surface quality verification. Material certificates and test reports available upon request.

Cost-Effective Solution: While stainless steel springs may have a higher initial cost than carbon steel alternatives, the extended service life, reduced maintenance requirements, and elimination of corrosion-related failures provide significant total cost of ownership benefits. Bulk order discounts and competitive wholesale pricing available for volume customers.

Installation / Usage Tips

Proper Alignment: Ensure compression force is applied parallel to the spring axis to prevent buckling and side loading. Misalignment can cause premature failure, uneven wear, and reduced spring life. Use guide rods or sleeves when necessary to maintain proper alignment during compression.

Avoid Over-Compression: Never compress the spring beyond its solid height (when all coils are touching). Over-compression causes permanent deformation, stress exceeding yield strength, and catastrophic spring failure. Design your application with appropriate travel limits to prevent bottoming out.

Operating Temperature Range: SS304 springs are suitable for temperatures from -40°C to 260°C (-40°F to 500°F). SS316 offers similar range with better performance at elevated temperatures. For extreme temperature applications, consult our engineering team for specialized material recommendations.

Regular Inspection & Maintenance: Implement a preventive maintenance schedule to inspect springs for signs of fatigue, wear, corrosion, or permanent deformation. Look for surface cracks, loss of free length, or changes in spring rate. Replace springs showing any degradation to prevent unexpected equipment failure.

Proper Storage: Store springs in a clean, dry environment away from corrosive atmospheres, chemicals, and extreme temperatures. Avoid storing springs in compressed state as this can cause stress relaxation over time. Keep springs in original packaging until installation.

Load Rate Considerations: Dynamic loading (rapid compression/decompression) generates higher stresses than static loading. For high-cycle or high-speed applications, consider specifying springs with higher safety factors. Our engineering team can assist with fatigue life calculations for your specific application.

Surface Protection: While stainless steel offers inherent corrosion resistance, additional protection may be beneficial in extremely aggressive environments. Consider passivation treatment to enhance the natural chromium oxide layer, or specify mirror finish for applications requiring maximum corrosion protection.
