C-210 vs Steatite
Ceramic · grade comparison
C-210 and Steatite are both ceramic grades. C-210 is the stronger of the two: tensile strength 70 MPa (10.2 ksi) against 60 MPa (8.7 ksi) for Steatite, about 17% more. C-210 is harder — 700 HV against 650 HV for Steatite — which matters for wear surfaces and threads. Steatite is lighter (2.8 g/cm³ vs 3.6 g/cm³ for C-210) and C-210 is stiffer (150 GPa vs 100 GPa). On the shop floor, C-210 sits in a lower cost tier (premium, $$$) than Steatite (high, $$$$).
C-210Choose it when strength drives the design, or when surface hardness matters.
SteatiteChoose it when weight is the constraint.
C-210 vs Steatite: 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.

C-210 vs Steatite — frequently asked
Is C-210 stronger than Steatite?
Yes. C-210 has a typical tensile strength of 70 MPa (10.2 ksi) against 60 MPa (8.7 ksi) for Steatite — about 17% more.
Which is cheaper, C-210 or Steatite?
C-210 is the lower-cost material: it sits in the premium tier ($$$) while Steatite is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose C-210 over Steatite?
Pick C-210 when strength drives the design, or when surface hardness matters. Pick Steatite when weight is the constraint.
