Carbon Steel Torsion Spring
Product Features & Applications
Our carbon steel torsion spring is manufactured from high-quality 65Mn carbon spring steel and 60Si2Mn alloy spring steel, featuring high mechanical strength, excellent toughness, strong compression resistance, and outstanding fatigue durability. It provides stable torque output with high load-bearing capacity while effectively preventing plastic deformation during long-term operation.
With mature manufacturing technology and neatly finished ends, the spring can also be customized with ground ends, special arm structures, and various non-standard designs according to different application requirements. Combining reliable performance with cost efficiency, it is widely recognized for its versatility in industrial use.
The carbon steel torsion spring is commonly applied in:
- Industrial machinery equipment
- Furniture hinges
- Door and window hardware
- Toy components
- General transmission and torsion systems
Its stable load performance allows continuous high-frequency torsion work without easy fatigue failure, making it suitable for both light-duty and heavy-duty mechanical applications.
