304 and 304L stainless steel are commonly selected for applications requiring a combination of corrosion resistance, formability, and suitable mechanical properties. The final wire specification should be selected according to the spring design, forming process, working environment, required mechanical condition, and applicable standard.

For technical purchasing, customers should confirm the material grade, wire diameter, surface finish, tolerance requirements, mechanical properties, and application requirements before production.

Product Specifications

Note: Tensile strength, hardness, dimensional tolerance, and other mechanical properties should be confirmed according to the selected diameter, production condition, applicable standard, and spring design requirements.

Material Selection: 304 vs 304L Stainless Steel Wire

304 Stainless Steel Spring Wire

AISI 304 stainless steel is one of the commonly used austenitic stainless steel grades for industrial wire applications.

It is widely considered for spring manufacturing and formed-wire components where corrosion resistance, processing performance, and mechanical requirements need to be balanced.

Typical factors for selecting 304 stainless steel wire include:

• Working environment
• Spring design requirements
• Forming process
• Required mechanical properties
• Surface requirements

304L Stainless Steel Spring Wire

304L is a low-carbon version of 304 stainless steel.

It can be selected when low-carbon stainless steel characteristics are required according to fabrication requirements or customer specifications.

The suitable grade should be determined according to the final application conditions and technical requirements.
