Technical Specifications
Product Overview
Metallurgical Characteristics
Tool Steel exhibits a martensitic microstructure after hardening with uniformly distributed carbides of chromium, tungsten, and vanadium. The fine carbide distribution provides exceptional wear resistance while maintaining adequate toughness. The controlled carbon content ensures optimal balance between hardness and machinability in the annealed condition.
Heat Treatment Process
MetalZenith employs controlled atmosphere hardening at 1020-1040°C followed by oil or air quenching and precision tempering at 150-200°C. Sub-zero treatment at -80°C may be applied to minimize retained austenite content and maximize dimensional stability for precision applications.
Manufacturing Process
Our Tool Steel production utilizes vacuum induction melting followed by electroslag remelting to ensure exceptional cleanliness and carbide uniformity. Controlled forging and rolling operations optimize grain flow and eliminate segregation, while precision machining and grinding services provide ready-to-use components.
Specialized Quality Testing
MetalZenith implements comprehensive testing protocols including Rockwell hardness distribution mapping across cross-sections, X-ray diffraction analysis for retained austenite quantification, metallographic examination of carbide size and distribution, and rotating beam fatigue testing to 10? cycles for critical applications.
Application-Specific Considerations
For cutting tool applications, optimal carbide distribution ensures extended tool life and superior edge retention. In die and mold manufacturing, controlled thermal treatment minimizes distortion and provides uniform hardness. Bearing applications benefit from exceptional dimensional stability and fatigue resistance, while precision mechanical components require tight tolerance control and surface finish optimization. Automotive applications demand consistent performance under cyclic loading and temperature variations.
