What is YT14 SINT?
YT14 SINT is YT14 in the SINT condition — standard uncoated YT14 for general steel turning, boring and milling on conventional machines. YT14 SINT has a tensile strength of 850 MPa (123 ksi), stronger than 81% of ceramic grades. Elongation at break is 0.1% and the elastic modulus is 520 GPa (75.4 Msi). YT14 SINT has a density of 11.4 g/cm³ (0.412 lb/in³), heavier than 81% of ceramic grades. It melts at 1,350°C (2,462 °F).
Advantages
- Tough — resists crack growth — 10.5 MPa·√m (9.56 ksi·√in), better than 89% of ceramic grades

Working with YT14 SINT
Is YT14 easy to machine?
Not machinable by conventional cutting — shape by diamond wheel grinding, wire/sinker EDM or green machining of the pressed blank before sintering.
Can YT14 be welded?
Not fusion weldable; joined to steel shanks by silver/copper brazing (Ag-Cu-Zn or Cu-Mn) with a ductile interlayer to absorb CTE mismatch.
Can YT14 be formed, bent or molded?
Made by wet-milled powder, press-and-sinter or extrusion of WC-TiC-Co feedstock, then vacuum or sinter-HIP at ~1450 °C; no post-sinter plastic forming.
What surface finishes work on YT14?
Diamond lapping and honing produce mirror rake faces; PVD/CVD hard coatings, edge honing and passivation are the usual value-adding steps.
YT14 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.

YT14 SINT — frequently asked
What is YT14 SINT used for?
YT14 SINT is typically used for general steel turning, milling of carbon/alloy steel and semi-finishing. In short: general-purpose steel grade; balanced wear and toughness; medium TiC content.
What is the tensile strength of YT14 SINT?
YT14 SINT has a typical tensile strength of 850 MPa (123 ksi) — stronger than 81% of ceramic grades. Strength varies by condition: see the 2 listed tempers.
Is YT14 SINT easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 59% of ceramic grades). Not machinable by conventional cutting — shape by diamond wheel grinding, wire/sinker EDM or green machining of the pressed blank before sintering.
Can YT14 SINT be welded?
Not fusion weldable; joined to steel shanks by silver/copper brazing (Ag-Cu-Zn or Cu-Mn) with a ductile interlayer to absorb CTE mismatch.
