Technical Specifications
Product Overview
Metallurgical Characteristics
VG10 exhibits a martensitic microstructure with fine, uniformly distributed carbides primarily composed of chromium and vanadium carbides. The high carbon content combined with strategic alloying elements provides exceptional hardness and wear resistance while maintaining adequate toughness for structural applications. The fine carbide distribution ensures superior edge retention and dimensional stability under load.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 1050-1080°C followed by rapid quenching in oil or controlled atmosphere. Tempering is performed at 150-200°C to achieve optimal hardness-toughness balance. Our precise temperature control and atmosphere management ensure consistent mechanical properties and minimize distortion during processing.
Manufacturing Process Excellence
Our VG10 production utilizes vacuum induction melting followed by electroslag remelting to achieve exceptional cleanliness and homogeneity. Controlled forging with optimized reduction ratios ensures proper carbide distribution and grain flow alignment. Advanced non-destructive testing including ultrasonic inspection and magnetic particle testing guarantees structural integrity.
Specialized Quality Testing
VG10 undergoes comprehensive evaluation including TIG and MIG welding performance testing with preheating protocols, cold bending and forming capability assessment, rotating beam fatigue testing up to 10? cycles, and salt spray atmospheric corrosion testing per ASTM B117. These tests ensure reliable performance in demanding structural environments.
Structural Application Engineering
For building frameworks, VG10 provides exceptional load-bearing capacity with reduced section requirements. In bridge construction, its fatigue resistance ensures long-term structural integrity under dynamic loading. Machinery applications benefit from superior wear resistance and dimensional stability. Automotive structural components achieve enhanced crash performance and weight optimization. General engineering applications leverage the combination of high strength and workability for complex structural geometries.
