Material Characteristics of SUS 302 Stainless Steel Wire

AISI 302 Stainless Steel for Spring Applications

AISI 302 stainless steel is an austenitic chromium-nickel stainless steel commonly used for stainless steel spring wire.

Through cold drawing and work hardening, the wire can achieve the mechanical condition required for different spring applications.

When selecting SUS 302 spring wire, manufacturers usually consider:

• Wire diameter
• Tensile strength requirement
• Spring design
• Forming process
• Surface condition
• Working environment

The final wire specification should match the actual spring manufacturing requirements.

Surface Options

Soap-Coated Stainless Steel Spring Wire

Soap coating provides a lubricated surface condition for selected spring coiling and wire forming processes.

It can be considered for applications requiring:

• Automatic spring coiling
• Wire feeding processes
• Cold forming operations
