SSiC F vs SSiC HIP
Ceramic · SSiC temper comparison
SSiC F and SSiC HIP are two conditions of the same ceramic grade, SSiC: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. SSiC HIP is harder — 2,700 HV against 2,500 HV for SSiC F — which matters for wear surfaces and threads. SSiC HIP is stiffer (440 GPa vs 410 GPa).
SSiC HIPChoose it when surface hardness matters.
SSiC F vs SSiC HIP: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all ceramic grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

SSiC F vs SSiC HIP — frequently asked
What is the difference between SSiC F and SSiC HIP?
SSiC F and SSiC HIP are two conditions of the same ceramic grade, SSiC: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. SSiC HIP is harder — 2,700 HV against 2,500 HV for SSiC F — which matters for wear surfaces and threads.
Which condition does FabDigit quote by default, F or HIP?
F is the default SSiC condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose SSiC F over SSiC HIP?
Pick SSiC HIP when surface hardness matters.
