What is the tensile strength of carbide cutting tool material?

Tungsten carbide grades used for cutting tools have transverse rupture strength (TRS) of 350,000–450,000 PSI (2,400–3,100 MPa). Unlike steel, carbide has negligible ductility and fails suddenly under tensile load. This high compressive-to-tensile strength ratio is why carbide tools are designed for compression.

How does temperature affect tensile strength?

Tensile strength decreases with increasing temperature. Steel at 400°C retains approximately 70% of room-temperature strength. Aluminum at 300°C retains about 20% of room-temperature strength. Superalloys like Inconel maintain 80–90% of strength at 600°C, which is why they're specified for high-temperature applications.

Does hardness predict tensile strength accurately?

Yes, for carbon and alloy steels. A common approximation: UTS (ksi) ≈ 500 × HRC for steels between 20–40 HRC. Above 40 HRC, use 490 + (HRC − 40) × 300 as a better approximation. ASTM E140 provides the most accurate conversion tables for hardness to tensile strength across different material families. ⚡ Calculated for Carbide-Tooling.com High-Performance Series.

1 PSI = 0,00689476 MPa. Para convertir PSI a MPa, divida por 145. Para convertir MPa a PSI, multiplique por 145. Para referencia común: 30.000 PSI (acero típico de bajo carbono) = 207 MPa. 100.000 PSI (acero de aleación común) = 690 MPa. 150.000 PSI (acero de alta resistencia) = 1.034 MPa. 200.000 PSI (acero maraging) = 1.379 MPa. Comprender ambas unidades es esencial para las especificaciones de ingeniería globales.	950	138
