Product Introduction
Xuanyu Springs offers comprehensive customized solutions for stainless steel torsion springs. We specialize in designing and manufacturing high-performance torsion springs for applications requiring high corrosion resistance and reliability, such as medical devices, precision instruments, automotive parts, and outdoor equipment, by utilizing the properties of different grades of stainless steel.
A stainless steel torsion spring is an elastic element that stores and releases angular energy by torsional deformation about its axis. It provides a restoring torque proportional to the angle during rotation. Thanks to the inherent corrosion resistance, rust prevention, and good elasticity of stainless steel, it is particularly suitable for precision mechanical structures operating in humid, clean, or long-term stable conditions.

Core parameters |
|
Material |
301 stainless steel : High yield strength, suitable for dynamic applications requiring extremely high elasticity and resistance to permanent deformation. |
|
302 stainless steel : Excellent comprehensive properties, balancing strength, elasticity and corrosion resistance, and has a wide range of applications. |
|
|
304/304L stainless steel : General-purpose austenitic stainless steel with good formability and corrosion resistance, suitable for food, chemical and general industrial environments. |
|
|
316/316L stainless steel : The addition of molybdenum significantly enhances its resistance to chloride corrosion, making it suitable for marine, medical, and highly corrosive environments. |
|
|
17-7PH (SUS631) : Precipitation hardening stainless steel that can be heat-treated to achieve extremely high strength while maintaining good corrosion resistance. |
|
|
wire diameter range |
Available in sizes from 0.1mm to 10.0mm , with support for non-standard customization to meet the needs of everything from micro-precision mechanisms to medium-sized industrial equipment. |
|
Torque and accuracy |
Torque values can be precisely designed to meet application requirements. The standard torque tolerance is ±10%, and products with higher precision levels (such as ±5%) are available . |
|
Surface treatment |
Stainless steel is typically kept in its original color (passivated to enhance corrosion resistance), but electropolishing and bright finishes are also available to meet special appearance or cleanliness requirements. |
|
Structural design |
Torque arm (leg) : Supports various forms such as straight arm, curved arm, and irregular arm. The length and angle can be flexibly designed to adapt to complex installation spaces. |
Advantages of Xuanyu Stainless Steel Torsion Springs
1. Professional material selection guidance and full range of supplies
We not only offer a full range of stainless steel materials from 302 and 304 to 316 and 17-7PH, but also provide professional selection advice based on your specific corrosion environment, strength requirements, operating temperature, and budget to ensure the best balance between spring performance and cost.
2. Strict control over cleanliness and consistency
For medical, food, or electronic applications, we offer cleaned springs with controlled surface residue. Rigorous process quality control ensures high consistency in dimensional and mechanical properties across every batch, guaranteeing smooth assembly and reliable end products.
3. In-depth non-standard customization and rapid response
Whether it's ultra-fine torsion springs for minimally invasive surgical instruments or large torsion springs for industrial valves, we support small-batch prototyping and rapid sample making. We can customize complex arm shapes, special torque curves, and stringent lifespan requirements.
