Technical Specifications
Product Overview
Metallurgical Characteristics
Hardox steel features a predominantly martensitic microstructure achieved through controlled quenching and tempering processes. The optimized alloy composition with chromium, nickel, and molybdenum additions provides exceptional hardenability and wear resistance while maintaining adequate toughness for structural applications. The fine-grained microstructure ensures uniform hardness distribution and superior mechanical properties.
Heat Treatment Process
MetalZenith employs precision-controlled austenitizing at 850-900°C followed by rapid quenching to achieve the desired martensitic structure. Subsequent tempering at 150-200°C optimizes the balance between hardness and toughness. Our advanced heat treatment facilities ensure uniform temperature distribution and controlled cooling rates for consistent mechanical properties.
Manufacturing Process Excellence
Our manufacturing process incorporates advanced electric arc furnace melting with secondary refining, continuous casting, and controlled rolling to achieve optimal chemical homogeneity and mechanical properties. Real-time process monitoring and automated quality control systems ensure consistent product quality and dimensional accuracy.
Specialized Quality Testing
MetalZenith conducts comprehensive testing including welding performance evaluation using standardized procedures, forming capability assessment through bend testing, fatigue strength testing under cyclic loading conditions, and atmospheric corrosion resistance testing in controlled environments to ensure long-term structural integrity.
Application Engineering Considerations
For building construction applications, Hardox provides exceptional durability in high-wear environments. In bridge engineering, its fatigue resistance ensures long service life under dynamic loading. For machinery manufacturing, the combination of hardness and toughness enables robust structural components. In vehicle manufacturing, weight optimization is achieved without compromising strength. For general engineering applications, excellent weldability and formability facilitate complex structural designs.
