Values for the HIP condition
What is T5K10 HIP?
T5K10 HIP is T5K10 in the HIP condition — pick the pressure-assisted sinter-HIP condition for near-zero porosity, higher transverse rupture strength and fatigue life in heavy interrupted cutting and large-section blanks. T5K10 HIP has a tensile strength of 900 MPa (131 ksi), stronger than 83% of ceramic grades. The elastic modulus is 540 GPa (78.3 Msi). T5K10 HIP has a density of 12.8 g/cm³ (0.462 lb/in³), heavier than 84% of ceramic grades. It melts at 1,370°C (2,498 °F).
Advantages
- Tough — resists crack growth — 12 MPa·√m (10.9 ksi·√in), better than 93% of ceramic grades
- Stiff — 540 GPa (78.3 Msi), better than 86% of ceramic grades
Limitations
- High embodied carbon — 30 kg CO₂/kg, worse than 91% of ceramic grades
- Heavy — 12.8 g/cm³ (0.462 lb/in³), worse than 84% of ceramic grades
- Needs corrosion protection — 50/100, worse than 83% of ceramic grades

Working with T5K10 HIP
Is T5K10 easy to machine?
After sintering it can only be shaped by diamond wheel grinding, EDM or laser cutting; conventional cutting is not possible.
Can T5K10 be welded?
Not fusion weldable; braze to steel shanks with silver-based Ag-Cu-Zn filler (BAg types) at 700–900 °C in vacuum or with a torch, then cool slowly to avoid braze cracking.
Can T5K10 be formed, bent or molded?
Powder-metallurgy pressing or extrusion followed by vacuum or low-pressure sintering at about 1400–1500 °C; sintering shrinkage is roughly 18–20% and no secondary plastic forming is possible.
What surface finishes work on T5K10?
Diamond grinding and lapping reaches Ra 0.05 µm; CVD/PVD coatings (TiN, TiCN, Al₂O₃) raise wear resistance, and electroplating is not suitable.
T5K10 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, raises red hardness and crater wear resistance | 4 – 6 | 5 |
| Cocobalt binder phase | 9 – 11 | 10 |
| WCtungsten carbide matrix, grain size about 1.5–3 µm | balance | — |
T5K10 HIP — frequently asked
What is T5K10 HIP used for?
T5K10 HIP is typically used for steel roughing turning inserts, brazed lathe tools for heavy interrupted cuts, planing and shaping tool tips, face milling inserts for forgings, machining of steel castings with scale and boring bar tips for rough passes. In short: tough steel-roughing carbide; interrupted-cut TiC grade; higher cobalt than Т15К6.
What is the tensile strength of T5K10 HIP?
T5K10 HIP has a typical tensile strength of 900 MPa (131 ksi) — stronger than 83% of ceramic grades.
Is T5K10 HIP easy to machine?
Not especially — machinability is rated not recommended (4/100, worse than 85% of ceramic grades). After sintering it can only be shaped by diamond wheel grinding, EDM or laser cutting; conventional cutting is not possible.
Can T5K10 HIP be welded?
Not fusion weldable; braze to steel shanks with silver-based Ag-Cu-Zn filler (BAg types) at 700–900 °C in vacuum or with a torch, then cool slowly to avoid braze cracking.

What is the maximum service temperature of T5K10 HIP?
T5K10 HIP is rated for continuous use to about 800°C (1,472 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
