Spring Tempered Stainless Steel Wire
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.
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.

Application Scope
Suitable for stainless steel springs, medical device fittings, food machinery accessories and anti-rust hardware components.
