What is YT30?
YT30 is a high-TiC WC-TiC-Co cemented carbide, the hardest and least tough member of the YT steel-cutting series. It is chosen for precision finishing of steel at high cutting speed and low feed, where dimensional stability and edge sharpness matter more than impact strength; forms are sintered inserts, brazed tips and blanks in SINT, HIP and coated conditions. Density is 9.5 g/cm3, elastic modulus 400 GPa, thermal conductivity 21 W/m·K and service temperature up to 1000 °C. Low toughness rules out interrupted cuts, heavy feeds and unstable setups; step down to YT15 when the cut is not continuous. YT30 has a density of 9.5 g/cm³ (0.343 lb/in³), heavier than 77% of ceramic grades. The elastic modulus is 400 GPa (58 Msi).
What is YT30 used for?
- precision steel finishing

Limitations
- High embodied carbon — 28 kg CO₂/kg, worse than 84% of ceramic grades

Physical2
YT30 has a density of 9.5 g/cm³ (0.343 lb/in³), heavier than 77% of ceramic grades.
Mechanical10
The elastic modulus is 400 GPa (58 Msi).
Thermal4
YT30 is rated for continuous service to 1,000°C (1,832 °F). It conducts heat at 21 W/m·K (12.1 BTU/hr·ft·°F), worse than 52% of ceramic grades. Thermal expansion is 7 µm/m·K (3.89 µin/in·°F).
Electrical2
YT30 has an electrical resistivity of 7×10⁻⁷ Ω·m.
Chemical & Environmental2
Corrosion resistance is good (58/100), worse than 72% of ceramic grades.
Sustainability4
Producing a kilogram of YT30 takes about 340 MJ of energy and emits 28 kg of CO₂ — more than 80% of ceramic grades. Typical recycled content is 25%.
Manufacturability3
YT30's machinability is not recommended (4/100, worse than 85% of ceramic grades).

Working with YT30
Is YT30 easy to machine?
Not machinable by conventional tools — shaped by diamond grinding, wire/sinker EDM or green machining before sintering.
Can YT30 be welded?
Not fusion weldable; attached by silver/copper brazing (Ag-Cu-Zn or Cu-Mn with Ni-plated interlayer), keeping heating and cooling slow to avoid cracks.
Can YT30 be formed, bent or molded?
Made by powder pressing (uniaxial or CIP) or extrusion of WC-TiC-Co powder, then vacuum/sinter-HIP densification at ~1450–1500 °C with ~18–22 % linear shrinkage.
YT30 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 small TaC/NbC additions | 28 – 32 | 30 |
| Cobinder phase | 3.5 – 4.5 | 4 |
| WCtungsten carbide balance | balance |
What surface finishes work on YT30?
Diamond wheel grinding, edge honing and diamond lapping give mirror surfaces; optional CVD/PVD TiN, TiCN or Al2O3 coatings for wear life.

YT30 — frequently asked
What is YT30 used for?
YT30 is typically used for precision steel finishing, high-speed light-cut turning and fine boring. In short: hardest grade in YT series; finishing cuts only; highest hot hardness, lowest toughness.
Is YT30 easy to machine?
Not especially — machinability is rated not recommended (4/100, worse than 85% of ceramic grades). Not machinable by conventional tools — shaped by diamond grinding, wire/sinker EDM or green machining before sintering.
Can YT30 be welded?
Not fusion weldable; attached by silver/copper brazing (Ag-Cu-Zn or Cu-Mn with Ni-plated interlayer), keeping heating and cooling slow to avoid cracks.

What is the maximum service temperature of YT30?
YT30 is rated for continuous use to about 1,000°C (1,832 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
