Technical Specifications
Product Overview
Metallurgical Characteristics
T10 exhibits a hypereutectoid microstructure with fine pearlite and spheroidized carbides in the annealed condition. Upon hardening, the steel transforms to a martensitic structure with retained carbides, providing exceptional hardness and wear resistance. The high carbon content ensures superior edge retention and cutting performance.
Heat Treatment Process
MetalZenith employs controlled heating to 780-800°C for hardening followed by water quenching to achieve maximum hardness. Tempering at 150-200°C optimizes the hardness-toughness balance. Our computer-controlled furnaces ensure uniform heating and precise temperature control throughout the process.
Manufacturing Process
Our T10 production utilizes vacuum induction melting to minimize inclusions, followed by controlled forging and rolling to achieve optimal grain flow. Spheroidizing annealing ensures uniform carbide distribution and excellent machinability in the soft condition.
Specialized Quality Testing
MetalZenith conducts comprehensive Rockwell hardness distribution mapping, residual austenite content measurement using X-ray diffraction, carbide distribution analysis through metallographic examination, and rotating beam fatigue testing to ensure consistent tool performance.
Application Engineering
For cutting tools, T10 provides excellent edge retention and sharpness. In cold forming dies, the high compressive strength and wear resistance ensure extended tool life. For precision instruments and small bearings, the dimensional stability and fine grain structure deliver superior accuracy. In automotive applications, the fatigue resistance and hardenability make it ideal for valve springs and precision components.
