Cemented Carbide WC-TiC-TaC-Co M20 vs Cemented Carbide WC-TiC-Co P20
Side-by-side chemical composition and mechanical property comparison.
Overview
Cemented Carbide WC-TiC-TaC-Co M20
ISO M20 multi-purpose cemented carbide with WC + TiC + TaC + Co. Bridges the gap between K (cast iron) and P (steel) grades. Moderate crater wear resistance from TiC/TaC with better toughness than pure P-grades. Hardness 90–91 HRA, density ~13.0–14.0 g/cm³, TRS 2000–2400 MPa. Applications: stainless steel (austenitic), heat-resistant alloys, ductile cast iron, mixed production. ANSI C7, China YW2.
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.
