Cemented Carbide WC-Co K40 vs Cemented Carbide WC-TiC-Co P20
Side-by-side chemical composition and mechanical property comparison.
Overview
Cemented Carbide WC-Co K40
ISO K40 cemented tungsten carbide with ~15% cobalt binder. Toughest standard WC-Co grade with highest impact resistance but lowest hardness. Hardness 89–90 HRA (~1200–1350 HV), density ~14.0 g/cm³, TRS 2800–3400 MPa. Coarse grain. Applications: heavy roughing of cast iron; cold heading dies; mining and rock drilling; punches and stamping tools; percussion bits; parts subject to heavy impact. ANSI C1/C11, China YG15.
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.
