Technical Specifications
Product Overview
Metallurgical Characteristics
Wootz steel exhibits a unique microstructure characterized by fine pearlitic matrix with dispersed carbide particles, providing exceptional strength and toughness. The high carbon content (1.2-1.8%) combined with controlled alloying elements creates a martensitic structure after quenching, offering superior mechanical properties for structural applications requiring high load-bearing capacity.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 850-900°C followed by oil quenching and tempering at 400-500°C to achieve optimal strength-toughness balance. The precise temperature control and cooling rates ensure uniform microstructure and minimize residual stresses critical for structural integrity.
Manufacturing Excellence
Our advanced crucible melting process ensures homogeneous carbon distribution and minimal inclusions. Controlled forging operations with precise temperature monitoring optimize grain flow and mechanical properties, while our quality control systems guarantee consistent performance across all production batches.
Structural Performance Testing
Comprehensive testing protocols include welding procedure qualification for structural joints, cold forming assessments for fabrication compatibility, fatigue strength evaluation under cyclic loading, and atmospheric corrosion resistance testing for long-term durability in various environmental conditions.
Engineering Applications
Wootz steel's exceptional strength-to-weight ratio makes it ideal for building frameworks requiring reduced structural weight, bridge construction demanding high load capacity, precision machinery manufacturing needing dimensional stability, automotive structural components requiring crash resistance, and general engineering applications where superior mechanical properties are essential for safety and performance.
