Working with YT15 SINT
Is YT15 easy to machine?
After sintering the material can only be shaped by diamond-wheel grinding, EDM or laser; pre-form geometry with carbide or HSS tools while the part is still in the green state.
Can YT15 be welded?
Not fusion weldable. Tips are brazed to steel shanks with silver-based filler (BAg-Cu-Zn) at 700-900 °C in vacuum or by torch, with slow cooling to avoid braze and carbide cracking.
Can YT15 be formed, bent or molded?
Formed by powder pressing (die pressing, isostatic pressing or extrusion) followed by vacuum liquid-phase sintering at 1400-1500 °C; allow for roughly 17-20 % linear shrinkage in the tooling.
What surface finishes work on YT15?
Diamond lapping and polishing reach Ra below 0.1 µm. CVD or PVD coatings can be applied, but the surface must be grit blasted and acid-treated to remove surface cobalt first.
YT15 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 | 14 – 16 | 15 |
| Cocobalt binder phase | 5.5 – 6.5 | 6 |

YT15 SINT — frequently asked
What is YT15 SINT used for?
YT15 SINT is typically used for steel finishing/semi-finishing, high-speed turning of steel and general lathe tooling. In short: classic steel-turning carbide; high hot hardness, moderate toughness; not for cast iron.
What is the tensile strength of YT15 SINT?
YT15 SINT has a typical tensile strength of 800 MPa (116 ksi) — stronger than 79% of ceramic grades. Strength varies by condition: see the 2 listed tempers.
Is YT15 SINT easy to machine?
Not especially — machinability is rated not recommended (4/100, worse than 85% of ceramic grades). After sintering the material can only be shaped by diamond-wheel grinding, EDM or laser; pre-form geometry with carbide or HSS tools while the part is still in the green state.
Can YT15 SINT be welded?
Not fusion weldable. Tips are brazed to steel shanks with silver-based filler (BAg-Cu-Zn) at 700-900 °C in vacuum or by torch, with slow cooling to avoid braze and carbide cracking.

What is the maximum service temperature of YT15 SINT?
YT15 SINT is rated for continuous use to about 900°C (1,652 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
