Product Features & Benefits
- Rust-Proof Performance: 304L stainless steel with low carbon content minimizes carbide precipitation, offering superior resistance to intergranular corrosion and oxidation. Ideal for outdoor, marine, or food processing equipment.
- Precise Dimensional Control: Wire diameter of 1.5mm and 15mm inner diameter are manufactured to tight tolerances, ensuring consistent torque output and easy integration into your assembly.
- 180° Working Angle: Designed for applications requiring a full half-turn rotation, such as clamps, hinges, and counterbalance mechanisms. The spring maintains stable force throughout its travel range.
- Enhanced Durability: Passivated surface removes free iron and contaminants, further improving corrosion resistance. The spring can withstand repeated cycles without fatigue failure.
- Customizable Options: Leg lengths, coil direction, end configurations (hooks, loops, straight ends) can be tailored to your specific requirements. Minimum order quantities are flexible for prototyping.
- Wide Application Range: Suitable for automotive components, electronic devices, agricultural machinery, and industrial automation. The spring performs reliably in temperatures from -20°C to 250°C.
Technical Advantages
| Aspect | Detail |
|---|---|
| Material Grade | 304L (UNS S30403) – Lower carbon content reduces weld decay and improves corrosion resistance in aggressive environments. |
| Manufacturing Process | Cold coiling on CNC spring machines, followed by stress relieving heat treatment to eliminate residual stresses. |
| Quality Control | 100% dimensional inspection using digital calipers and load testing on sample batches. Certificates of analysis available upon request. |
| Packaging | Individually wrapped in anti-corrosion paper then packed in carton boxes with foam inserts for safe transit. |

Frequently Asked Questions
-
Q: Can this spring be used in outdoor applications?
A: Yes. The 304L stainless steel material provides excellent corrosion resistance against rain, humidity, and UV exposure. It is suitable for gates, outdoor furniture, and marine equipment. -
Q: What is the maximum torque this spring can handle?
A: The torque depends on the number of active coils and leg configuration. For a standard spring with 10 active coils, the approximate torque at 180° is 0.5 N·m. Contact us for a detailed calculation for your specific design. -
Q: Do you offer other wire diameters or inner diameters?
A: Yes, we can produce springs with wire diameters from 0.5mm to 8mm and inner diameters from 5mm to 100mm. Custom dimensions are available upon request. -
Q: Is there a minimum order quantity?
A: For standard sizes, there is no strict MOQ. For custom springs, a minimum order of 100 pieces is typically required. Small samples can be provided for testing. -
Q: How long does production take?
A: For standard springs, lead time is 7–10 working days. Custom orders usually require 15–20 working days depending on complexity and quantity. -
Q: Can you provide a material certificate?
A: Yes, we can provide a mill test certificate for the 304L stainless steel wire upon request. Additional testing reports (e.g., hardness, tensile strength) are also available. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and Western Union. For new customers, a 30% deposit is required, with the balance paid before shipment. -
Q: How do you ensure the spring's rust-proof property?
A: The 304L grade inherently resists rust, and we apply a passivation treatment to remove surface contaminants. Regular salt spray tests (e.g., 48-hour neutral salt spray) confirm the treatment's effectiveness.
