The 50CrV4 Alloy Spring Steel Wire is a high-performance alloy wire engineered for demanding mechanical and industrial applications. Produced from 50CrV4 steel, this wire exhibits exceptional tensile strength, excellent fatigue resistance, and stable wear and corrosion resistance. Each batch complies with international standards including ASTM, ISO, and GB/T, and comes with complete material certificates (MTC), mechanical test reports, and optional third-party inspection to ensure reliability and traceability. Its uniform diameter, smooth surface finish, and consistent mechanical properties make it ideal for precision springs and high-strength components.
Material Highlights:
- Composition: Carbon 0.47–0.55%, Chromium 0.9–1.2%, Vanadium 0.15–0.25%, Manganese 0.50–0.80%
- Mechanical Properties: High tensile and yield strength, excellent fatigue life
- Quality Assurance: MTC available, third-party inspection optional
