Custom stainless steel compression springs manufactured in 301,302, 304,316 and 17-7PH stainless steel for corrosion-resistant applications. Designed according to customer drawings, samples and technical specifications for OEM industries worldwide.
GL Springs manufactures custom stainless steel compression springs for applications requiring corrosion resistance, consistent spring force and reliable performance. Each spring can be produced according to customer drawings, physical samples or technical specifications, with customized wire diameter, outside diameter, free length, spring rate, load and end configuration.
Stainless steel compression springs are commonly selected for wet, humid, outdoor, washdown and mildly corrosive environments. Compared with ordinary carbon steel springs, stainless steel provides better corrosion resistance and can reduce the need for additional protective coatings in many applications.
We support prototype development, small-batch production and repeat volume orders for industrial equipment, automotive components, electronics, medical equipment, food-processing machinery, valves and other OEM assemblies.
A compression spring stores energy when an axial force compresses its coils. Its performance depends on the relationship between material, wire diameter, mean coil diameter, active coil count, free length and operating deflection.
GL Springs does not limit customers to standard catalog dimensions. We manufacture made-to-drawing stainless steel compression springs based on the required installation space, working load, spring rate, operating stroke and service environment.
For a new project, customers may provide a PDF drawing, CAD file, dimensional sketch, physical sample or application requirements. Our team can review the information and assist with manufacturability, material selection and prototype preparation through our custom spring design service.
The appropriate stainless steel grade depends on corrosion exposure, temperature, mechanical performance, fatigue requirements and cost targets.
| Material | Typical Characteristics | Typical Applications |
|---|---|---|
| Stainless Steel 304 | Good general corrosion resistance, widely available and suitable for many industrial environments. | Industrial equipment, electronics, household products, general mechanical assemblies. |
| Stainless Steel 316 | Improved resistance to moisture, salts and certain corrosive environments compared with 304. | Marine-related equipment, outdoor products, valves and wet environments. |
| Stainless Steel 316L | Low-carbon version of 316, commonly considered where corrosion resistance and fabrication requirements are important. | Process equipment, instruments and specialized OEM assemblies. |
| 17-7PH / SUS 631 | Precipitation-hardening stainless steel offering higher strength and good spring properties. | Precision components, higher-stress applications and demanding spring assemblies. |
Final material selection should be based on the actual working environment and required spring performance. Send us your operating conditions and drawing so that the material can be evaluated before quotation.
304 and 316 are two commonly requested materials for custom stainless steel compression springs. The correct choice depends on the operating environment rather than simply selecting the more expensive grade.
Material grade alone does not determine service life. Spring stress, compression stroke, operating cycles, temperature and surface condition must also be considered.

The spring end configuration affects stability, installed height, load distribution and seating performance. Available options include:
The end style should be defined on the drawing or selected according to the installation method and performance requirements.
Stainless steel springs are frequently used without decorative coatings because the base material already provides corrosion resistance. Additional finishing may still be requested for cleanliness, appearance or environmental performance.
Surface treatment requirements should be stated during quotation because they may affect manufacturing cost, testing and lead time.
Custom stainless steel compression springs can be used in a wide range of products and assemblies, including:
Suitability for a particular regulated or safety-critical application must be confirmed against the customer's drawing, specification and validation requirements.
GL Springs manufactures custom springs under ISO 9001 and IATF 16949 quality management systems. Inspection requirements can be arranged according to the drawing, product characteristics and order requirements.
Typical inspection items may include:

Prototype production helps customers verify fit, load, deflection and assembly performance before releasing a design for volume production. GL Springs can prepare custom samples according to approved drawings or technical requirements.
For new projects, please review our custom spring prototyping and sample service. Prototype timing depends on material availability, dimensions, tooling, finishing and inspection requirements.
For an accurate quotation, please provide as much of the following information as possible:
When a complete drawing is not available, send the installation dimensions, required force and working stroke. Our team can review the information through the spring design and engineering process.
Yes. Springs can be manufactured from PDF drawings, CAD files, dimensional specifications or approved physical samples. The drawing should ideally include material, wire diameter, spring diameter, free length, end style and load requirements.
304 is suitable for many general industrial applications. 316 is commonly selected for applications involving moisture, salt exposure, outdoor use or more corrosive environments. The final choice should consider spring stress, temperature, fatigue life and the complete service environment.
Yes. 316L can be supplied when required by the customer drawing or material specification.
Yes. Passivation is available, and electropolishing can be arranged when specified. Please include the required surface finish in the RFQ.
Yes. Spring load and spring rate are designed according to the material, wire diameter, coil diameter, active coils and working deflection stated in the drawing or application requirements.
Yes. Prototype and sample production are available for dimensional, load and assembly validation before volume production.
MOQ depends on spring dimensions, material, process, surface finish and inspection requirements. Prototype quantities and production quantities should be stated separately when requesting a quotation.
