Product Description
Stainless Steel Helical Spring Engineered Corrosion Resistance
In aggressive environments—from coastal marine facilities to chemical processing plants—compression springs face relentless attack from moisture, salt spray, and chemical vapors that degrade conventional materials. Our Stainless Steel Helical Springs are engineered to thrive in these conditions, leveraging advanced alloy formulations and precision manufacturing to deliver unmatched corrosion resistance and mechanical performance.
Material Specifications
Primary Materials:
Medical-grade 316L stainless steel (UNS S31603), precipitation-hardened 17-4 PH stainless steel
Corrosion Resistance:
Pitting Resistance Equivalent Number >40, validated through 1,000-hour salt spray testing per ASTM B117
Surface Finish:
Electropolished (Ra <0.2μm), eliminating micro-pores where corrosion initiates
Engineering & Manufacturing Excellence
Our engineering process integrates CAD (SolidWorks 2024) with FEA (ANSYS Mechanical) simulations to optimize coil geometry for both corrosion resistance and mechanical efficiency. Manufacturing adheres to ISO 13485 standards with cleanroom production (Class 8) to prevent particulate contamination.
Key Performance Features:
- Precise load-deflection characteristics (±2% tolerance across 0.5-200 N/mm spring rates)
- Variable pitch designs reduce stress concentrations by 35% compared to uniform coils
- Extended fatigue life to 10⁶ cycles at 80% of yield strength
- Tensile strengths up to 1,200 MPa
- Heat treatment in nitrogen-atmosphere furnaces at 1050°C
