Grade: ZHD86 grain size: 2.0 Hardness: 86.0 Density: 13.4 Usage: suitable for playing straight bar, six die, etc., suitable for playing low-carbon steel, small size stainless steel, copper, aluminum, etc., as well as strain hardening phase is a single element cycles Table transition metal carbides, such as tungsten carbide, titanium carbide, tantalum, their hardness is engaged, melting point above 2000 ℃, and some even more than 4000 ℃. In addition, transition metal oxides, borides, silicides have similar characteristics, but also can act as a hardening phase in the cemented carbide. Determine the presence of the hardening phase of the alloy with high.
