Technical Specifications
Product Overview
Metallurgical Characteristics
S35VN exhibits a martensitic microstructure with fine, uniformly distributed vanadium and niobium carbides. The powder metallurgy production process ensures exceptional carbide distribution and eliminates segregation issues common in conventionally melted steels. The refined microstructure provides superior toughness while maintaining high hardness and wear resistance essential for structural applications.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 1065-1095°C followed by rapid quenching and precise tempering at 200-400°C depending on target hardness requirements. Our computer-controlled heat treatment ensures optimal transformation kinetics and stress relief while maintaining the fine carbide structure critical for structural performance.
Manufacturing Process
Our S35VN production utilizes advanced vacuum induction melting followed by argon atomization to create fine, spherical powder particles. The powder is then consolidated using hot isostatic pressing (HIP) at controlled temperature and pressure, resulting in full density and superior mechanical properties compared to conventional casting and forging methods.
Structural Quality Testing
MetalZenith conducts comprehensive testing protocols including welding performance evaluation using standard AWS procedures, forming capability assessment through bend testing, fatigue strength analysis using rotating beam testing, and atmospheric corrosion resistance testing per ASTM G50 standards. These specialized tests ensure optimal performance in demanding structural environments.
Application Engineering Considerations
For building structures, S35VN provides exceptional strength-to-weight ratios enabling lighter framework designs. In bridge engineering, the superior fatigue resistance ensures long-term durability under cyclic loading. For machinery manufacturing, the excellent machinability and dimensional stability facilitate precision component production. In vehicle manufacturing, the high strength enables weight reduction while maintaining safety standards. General engineering applications benefit from the versatile processing capabilities and consistent mechanical properties.
