What is YT15 HIP?

YT15 HIP is YT15 in the HIP condition — choose sinter-HIP consolidation to remove residual porosity for higher transverse rupture strength and edge reliability in precision inserts and light interrupted cutting. YT15 HIP has a tensile strength of 950 MPa (138 ksi), stronger than 85% of ceramic grades. Elongation at break is 0.1% and the elastic modulus is 530 GPa (76.9 Msi). YT15 HIP has a density of 11.5 g/cm³ (0.415 lb/in³), heavier than 82% 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 YT15 HIP

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 HIP — frequently asked

What is YT15 HIP used for?

YT15 HIP 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 HIP?

YT15 HIP has a typical tensile strength of 950 MPa (138 ksi) — stronger than 85% of ceramic grades. Strength varies by condition: see the 2 listed tempers.

Is YT15 HIP easy to machine?

Not especially — machinability is rated not recommended (3/100, worse than 95% 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 HIP 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 HIP?

YT15 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.
