Sandvik DH40 Cemented Carbide for Woodworking (discontinued **)
Categories:	Ceramic; Carbide; Metal; Metal Matrix Composite; Nonferrous Metal; Tungsten Alloy
Material Notes:	The unique grain size distribution is optimized to improve the toughness and the micro crack resistance The composition of the DH grades includes specific additions to increase the thermal resistance (thermal cycling fatigue), and the corrosion/oxidation resistance This combination of innovations gives the DH grades a high edge retention and crack resistance. These properties, combined with a good brazeability and grindibility, allow the DH grades family to be very efficient when looking at cost/performance ratio. Features: Medium grain size Moderate to medium abrasion resistance High impact strength Binderphase content 11% Codes: ISO K40 Information provided by Sandvik
