Technical Specifications
Product Overview
Metallurgical Characteristics
T15 exhibits a complex carbide structure with primary MC carbides (vanadium-rich) and secondary M6C carbides (tungsten-molybdenum rich) distributed in a martensitic matrix. The cobalt addition enhances red hardness and thermal stability, while the high vanadium content provides exceptional wear resistance through hard vanadium carbide formation.
Heat Treatment Process
MetalZenith employs controlled austenitizing at 1200-1230°C followed by rapid quenching in salt baths or vacuum furnaces. Triple tempering at 540-560°C ensures optimal secondary hardness and carbide precipitation while minimizing retained austenite content below 8%.
Advanced Manufacturing Process
Our production utilizes vacuum induction melting followed by electroslag remelting to achieve superior cleanliness and carbide distribution. Controlled forging and rolling operations ensure proper carbide alignment and eliminate segregation, critical for tool performance consistency.
Specialized Quality Testing
MetalZenith conducts comprehensive Rockwell hardness distribution mapping across tool sections, retained austenite analysis using X-ray diffraction, carbide size and distribution evaluation through metallographic analysis, and rotating beam fatigue testing to ensure optimal tool life performance.
Application-Specific Considerations
For cutting tool applications, T15 provides superior edge retention and thermal stability. In die and mold manufacturing, its high compressive strength and wear resistance ensure extended service life. For bearing components, the material offers excellent dimensional stability and fatigue resistance. In precision machinery and automotive applications, T15 delivers consistent performance under high-stress conditions with minimal thermal distortion.
