What is YW2 HIP?
YW2 HIP is YW2 in the HIP condition — choose low-pressure sinter-HIP when porosity must be eliminated for higher transverse rupture strength and toughness in interrupted cutting and heavy roughing. YW2 HIP has a tensile strength of 1,100 MPa (160 ksi), stronger than 88% of ceramic grades. Elongation at break is 0% and the elastic modulus is 545 GPa (79 Msi). YW2 HIP has a density of 13.1 g/cm³ (0.473 lb/in³), heavier than 87% of ceramic grades. It melts at 1,320°C (2,408 °F). SINT is the default condition FabDigit quotes; HIP is available on request or by drawing note.

Working with YW2 HIP
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.
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 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.

|---|---|---|
| Cobinder phase | 7.5 – 8.5 | 8 |
| TiCcrater wear resistance | 5 – 7 | 6 |

YW2 HIP — frequently asked
What is YW2 HIP used for?
YW2 HIP 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 HIP?
YW2 HIP has a typical tensile strength of 1,100 MPa (160 ksi) — stronger than 88% of ceramic grades. Strength varies by condition: see the 2 listed tempers.
Is YW2 HIP 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.
Can YW2 HIP be welded?

What is the maximum service temperature of YW2 HIP?
YW2 HIP 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.
