Technical Specifications
Product Overview
Metallurgical Characteristics
High Carbon Chromium Steel exhibits a martensitic microstructure after quenching with fine carbide precipitation during tempering. The high carbon content (0.95-1.10%) provides exceptional hardness and wear resistance, while chromium addition (1.30-1.60%) enhances hardenability and corrosion resistance. The controlled carbide distribution ensures optimal balance between hardness and toughness for high-strength applications.
Heat Treatment Process
MetalZenith employs precise austenitizing at 820-860°C followed by oil or water quenching to achieve full martensitic transformation. Subsequent tempering at 150-200°C optimizes the strength-toughness balance while maintaining high hardness levels. Our controlled atmosphere processing prevents decarburization and ensures consistent mechanical properties throughout the cross-section.
Manufacturing Excellence
MetalZenith utilizes vacuum induction melting followed by electroslag remelting to achieve superior cleanliness and homogeneity. Our advanced forging and rolling processes with controlled deformation ratios ensure optimal grain flow and mechanical properties. Precision machining capabilities enable tight dimensional tolerances for critical high-strength components.
Specialized Quality Testing
Comprehensive testing protocols include formability assessment through bend testing and deep drawing evaluation, weldability studies with preheating requirements, hydrogen-induced cracking resistance testing per NACE standards, and delayed fracture evaluation under sustained loading conditions. Advanced ultrasonic and magnetic particle inspection ensures defect-free material delivery.
Application Engineering
For automotive applications, optimized chemistry ensures excellent fatigue resistance in engine components and transmission parts. Building and bridge applications benefit from superior yield strength and controlled weldability with appropriate preheating procedures. Pressure vessel applications utilize the high tensile strength and proven resistance to hydrogen embrittlement, while crane and lifting equipment applications leverage the exceptional fatigue performance and impact resistance.
