Values for the SINT condition
YW2 tempers and conditions
YW2 is supplied in 2 conditions, soft to hard. SINT is the default FabDigit quotes; the values on this page are for it.
Compare all 2 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
SINTDefault Sintered | Use the conventional vacuum liquid-phase sintered blank or insert for general rough and semi-finish turning where cost matters more than peak edge strength. | 1,000 | 0 | 1,450 HV | 30 W/m·K | |
Hot isostatic pressed | Choose low-pressure sinter-HIP when porosity must be eliminated for higher transverse rupture strength and toughness in interrupted cutting and heavy roughing. | 1,100 | 0 | 1,470 HV | 31 W/m·K |
What is YW2?
YW2 is a WC-TiC-TaC(NbC)-Co universal cemented carbide adjusted for slightly higher toughness than YW1, at the cost of some hardness. It is used for roughing through semi-finishing of stainless and heat-resistant steels and for general lathe and mill tooling, supplied as sintered inserts, brazed tips and blanks in SINT, HIP and coated conditions. Density is 13 g/cm3 and service temperature about 900 °C. Because hardness is lower, it is not the best choice for high-speed finish passes where surface finish and crater wear govern; YW1 or YT30 are the alternatives for that duty. YW2 has a density of 13 g/cm³ (0.47 lb/in³), heavier than 86% of ceramic grades. It melts at 1,320°C (2,408 °F). YW2 has a tensile strength of 1,000 MPa (145 ksi), stronger than 85% of ceramic grades. Elongation at break is 0% and the elastic modulus is 540 GPa (78.3 Msi).

Working with YW2
Is YW2 easy to machine?
Diamond-wheel grinding, EDM or laser only; conventional turning and milling are not possible. Flood cool during grinding to prevent thermal cracking.
Can YW2 be welded?
Not fusion weldable. Inserts and tips are vacuum or induction brazed to steel bodies with silver-based (BAg-type) filler, then cooled slowly to limit residual stress.
Can YW2 be formed, bent or molded?
Powder blending, pressing or extrusion, dewaxing, then vacuum or low-pressure HIP liquid-phase sintering; linear shrinkage is about 18-20 %, so tooling must be sized to the shrink factor.
YW2 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 |
|---|---|---|
| Cobinder phase | 7.5 – 8.5 | 8 |
| TiCcrater wear resistance | 5 – 7 | 6 |
| TaC+NbCrefines grain, raises high-temperature strength | 3 – 5 | 4 |
| WCbalance; grain size about 1–3 µm | balance |
What surface finishes work on YW2?
Diamond grinding and polishing give mirror cutting edges. CVD (TiN/TiCN/Al2O3) or PVD (TiAlN) coatings can be applied, and blast honing of the edge improves chipping resistance.

YW2 — frequently asked
What is YW2 used for?
YW2 is typically used for stainless steel roughing, heat-resistant alloy machining and general lathe/mill tooling. In short: tougher universal grade; roughing to semi-finishing; handles interrupted cuts.
What is the tensile strength of YW2?
YW2 has a typical tensile strength of 1,000 MPa (145 ksi) — stronger than 85% of ceramic grades. Strength varies by condition: see the 2 listed tempers.
Is YW2 easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 59% of ceramic grades). Diamond-wheel grinding, EDM or laser only; conventional turning and milling are not possible. Flood cool during grinding to prevent thermal cracking.
