What is YT14?
YT14 is a WC–TiC–Co cemented carbide with a medium TiC content, supplied as-sintered (SINT), sinter-HIP (HIP) or CVD-coated, and belongs to the ISO P group for steel. It is the general-purpose choice for turning and milling carbon and alloy steel, balancing the crater-wear resistance of the cubic carbide against enough toughness for semi-finishing; forms include pressed inserts, brazed tips and blanks. Thermal conductivity is only 33 W/m·K and edge temperature is limited to about 900 °C, so it is not a cast-iron or aluminium grade; corrosion resistance is moderate (score 52). Use YT5 for rougher, more interrupted cuts. YT14 has a density of 11.4 g/cm³ (0.412 lb/in³), heavier than 81% of ceramic grades. It melts at 1,350°C (2,462 °F). YT14 has a tensile strength of 850 MPa (123 ksi), stronger than 81% of ceramic grades. Elongation at break is 0.1% and the elastic modulus is 520 GPa (75.4 Msi).
What is YT14 used for?

- Heavy — 11.4 g/cm³ (0.412 lb/in³), worse than 81% of ceramic grades
- Needs corrosion protection — 52/100, worse than 81% of ceramic grades

Working with YT14
Is YT14 easy to machine?
Not machinable by conventional cutting — shape by diamond wheel grinding, wire/sinker EDM or green machining of the pressed blank before sintering.
Can YT14 be welded?
Not fusion weldable; joined to steel shanks by silver/copper brazing (Ag-Cu-Zn or Cu-Mn) with a ductile interlayer to absorb CTE mismatch.
Can YT14 be formed, bent or molded?
Made by wet-milled powder, press-and-sinter or extrusion of WC-TiC-Co feedstock, then vacuum or sinter-HIP at ~1450 °C; no post-sinter plastic forming.
YT14 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| TiCtitanium carbide, may include minor TaC/NbC in some producers' variants | 13 – 15 | 14 |
| Cobinder phase | 7.5 – 8.5 | 8 |
| WCbalance, medium grain 1.5–3 µm | balance |
What surface finishes work on YT14?
Diamond lapping and honing produce mirror rake faces; PVD/CVD hard coatings, edge honing and passivation are the usual value-adding steps.

YT14 — frequently asked
What is YT14 used for?
YT14 is typically used for general steel turning, milling of carbon/alloy steel and semi-finishing. In short: general-purpose steel grade; balanced wear and toughness; medium TiC content.
What is the tensile strength of YT14?
YT14 has a typical tensile strength of 850 MPa (123 ksi) — stronger than 81% of ceramic grades. Strength varies by condition: see the 2 listed tempers.
Is YT14 easy to machine?
