What is YT30 HIP?
YT30 HIP is YT30 in the HIP condition — choose when pore-free structure and the highest attainable transverse rupture strength/edge reliability are required. The elastic modulus is 405 GPa (58.7 Msi). YT30 HIP has a density of 9.55 g/cm³ (0.345 lb/in³), heavier than 78% of ceramic grades. SINT is the default condition FabDigit quotes; HIP is available on request or by drawing note.
Advantages
- Polishes to a fine finish — 90/100, better than 78% of ceramic grades
- Tough — resists crack growth — 7.5 MPa·√m (6.83 ksi·√in), better than 76% of ceramic grades
Limitations
- High embodied carbon — 28 kg CO₂/kg, worse than 84% of ceramic grades
- Heavy — 9.55 g/cm³ (0.345 lb/in³), worse than 78% of ceramic grades
YT30 HIP properties
Typical room-temperature values for YT30 HIP; 15 are specific to this condition. Other listed values are YT30 reference data and may not represent this condition. Bars are the position among ceramic grades.
Physical2
YT30 HIP has a density of 9.55 g/cm³ (0.345 lb/in³), heavier than 78% of ceramic grades.
Mechanical10
The elastic modulus is 405 GPa (58.7 Msi).
Thermal4
YT30 HIP is rated for continuous service to 1,000°C (1,832 °F). It conducts heat at 21.5 W/m·K (12.4 BTU/hr·ft·°F), better than 50% of ceramic grades. Thermal expansion is 7 µm/m·K (3.89 µin/in·°F).
Electrical2
YT30 HIP has an electrical resistivity of 6.8×10⁻⁷ Ω·m.
Chemical & Environmental2
Corrosion resistance is good (60/100), worse than 71% of ceramic grades.
Sustainability4
Producing a kilogram of YT30 HIP 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 HIP's machinability is not recommended (3/100, worse than 95% of ceramic grades).
Values are nominal handbook figures for design screening. Confirm any required mill or lot documentation when quoting.
Working with YT30 HIP
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.
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 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 |

YT30 HIP — frequently asked
What is YT30 HIP used for?
YT30 HIP 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 HIP easy to machine?
Not especially — machinability is rated not recommended (3/100, worse than 95% of ceramic grades). Not machinable by conventional tools — shaped by diamond grinding, wire/sinker EDM or green machining before sintering.
Can YT30 HIP 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 HIP?
YT30 HIP 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.
