High Carbon Spring Steel Wire 0.127-20mm Diameter 55CrSi 65Mn Grade for Mechanical Springs

High Carbon Spring Steel Wire is engineered for exceptional performance in demanding applications. Available in diameters ranging from 0.127mm to 20mm, this non-alloy steel wire in grades 55CrSi and 65Mn provides superior mechanical properties for spring manufacturing and mechanical components.

Spring steel wire operates within the elastic range, returning to its original position after unloading with minimal plastic deformation. The material delivers:

• High elastic limit and yield strength for maximum energy storage
• Superior tensile strength ensuring reliable performance under load
• Excellent fatigue resistance for long service life under alternating stress
• Outstanding creep and relaxation resistance maintaining dimensional stability

Our spring steel wire meets multiple international standards including GB, ASTM, JIS, DIN, NF, BS, OCT, and ISO specifications.

• Quality First: Strict adherence to production standards throughout manufacturing and inspection
• Competitive Pricing: Market-based pricing with volume discounts
• Transaction Security: Complete financial protection for all orders
• Comprehensive After-Sales: Full support for customer requirements
• Long-Term Partnership: Consistent quality and service for ongoing cooperation
