TDSiCr Oil Hardened and Tempered Steel Wire
Premium Spring Steel Solutions by FUSHUN METAL
Steel Grade Introduction and Applications
TDSiCr is a high-silicon chromium-vanadium oil hardened and tempered steel wire engineered for demanding spring applications requiring exceptional elastic properties and high-temperature performance. This premium grade steel from FUSHUN METAL offers superior elastic limit, excellent fatigue resistance, and outstanding corrosion resistance, making it the ideal choice for automotive valve springs, high-stress suspension springs, and precision mechanical components operating under severe conditions.
The high silicon content significantly enhances elastic properties and resistance to permanent set, while the chromium-vanadium combination provides excellent hardenability and wear resistance, ensuring consistent performance in high-temperature and high-stress environments where reliability is paramount.
