Spring Tempered Stainless Steel Wire

Spring tempered stainless steel wire is stainless steel wire finished with tempering stabilization treatment, combining stainless steel's inherent anti-corrosion performance and the convenience of tempered wire, which can be directly coiled into springs without secondary heat treatment.
We supply multi-grade spring tempered stainless steel wire including SUS304, SUS316, SUS201 and SUS631, wire diameter 0.2mm–6.0mm. Integrated cold drawing and tempering processes eliminate internal residual stress, ensuring stable elasticity and smooth forming performance of each spring tempered stainless steel wire.

Product Introduction
 

Unique Tempered Stainless Steel Advantages

 

Permanent corrosion resistance

Stainless steel base material avoids rust and oxidation under long-term humid and mildly corrosive working conditions.

Consistent elastic performance

Tempering treatment stabilizes elastic modulus to achieve uniform rebound force of finished springs.

Excellent forming toughness

Low breakage rate during coiling and bending, improving production yield.

No secondary thermal processing needed

Directly fabricated into finished springs to skip complex stainless steel heat treatment procedures and avoid forming deformation.

 

 

Surface & Mechanical Performance

 

Bright finish and matte finish are optional. Tensile strength ranges 1300MPa–2100MPa based on material grade and wire diameter with stable and reliable mechanical indicators.
