Properties & Applications of Cemented Carbide Cutting Tools (1)

YT30:its density is 9.5 with bending strength up to 1140 and the relevant hardness is 92.5. In terms of performance its wear resistance and cutting speed higher than YT15 but strength and impact toughness comparatively lower finishing of carbon steel and alloy steel,for instance fine turning,boring or fine reaming or their small chip sections.

YT15:its density is11.3 with bending strength up to 1650 and the relevant hardness is 92. In terms of performance its wear resistance higher than YT5,but impact toughness lower than YT5,semi-finishing of the medium chip sections of steel .cast steel and alloy steel or finishing or their small chip sections

YT5:its density is12.9 with bending strength up to 2200and the relevant hardness is 90.5. In terms of performance it has best strength and high impact &shock resistance among W-Co-Tialloys but wear resistance comparatively lower.Rough turning rough planing and half precision planing of carbon steel and alloy steel(including forged steel parts,stamped parts and cast iron surfaces).
