Abstract
A cemented carbide comprising 55-90 parts by mass of WC particles, and 10-45 parts by mass of an Fe-based binder phase, the binder phase having a composition comprising 2.5-10% by mass of Ni, 0.2-1.2% by mass of C, 0.5-5% by mass of Cr, 0.2-2.0% by mass of Si, 0.1-3% by mass of W, 0-5% by mass of Co, and 0-1% by mass of Mn, the balance being substantially Fe and inevitable impurities, and the cemented carbide being substantially free from composite carbides having major axes of 5 μm or more. This cemented carbide is produced by cooling at a cooling rate of 60° C./hour or more between 900° C. and 600° C., after vacuum sintering.
