Cemented Carbide WC-Co K20 vs Cemented Carbide WC-TiC-Co P20
Side-by-side chemical composition and mechanical property comparison.
Overview
Cemented Carbide WC-Co K20
ISO K20 cemented tungsten carbide with ~8% cobalt binder. The most widely used general-purpose WC-Co grade, balancing wear resistance and toughness. Hardness 91–92 HRA (~1450–1550 HV), density ~14.7 g/cm³, TRS 2200–2600 MPa. Medium grain. Applications: general turning, milling, drilling of cast iron, non-ferrous metals; end mills; wear parts with light impact; mining bits. ANSI C2, China YG8.
Cemented Carbide WC-TiC-Co P20
ISO P20 cemented carbide with WC + TiC/TaC + Co. Designed for machining steel and steel castings. TiC addition provides crater wear resistance essential for steel cutting. Hardness 91–92 HRA, density ~12.0–13.0 g/cm³ (lower than K-grades due to TiC), TRS 1800–2200 MPa. Applications: general turning, milling, planing of carbon steel, alloy steel, tool steel, ferritic and martensitic stainless steel. ANSI C6, China YT15.
