C2 vs YG8C

Ceramic · grade comparison

C2 and YG8C are both ceramic grades. C2 is the stronger of the two: tensile strength 1,200 MPa (174 ksi) against 1,100 MPa (160 ksi) for YG8C, about 9% more. C2 is harder — 1,580 HV against 1,220 HV for YG8C — which matters for wear surfaces and threads.

C2Choose it when strength drives the design, or when surface hardness matters.

C2 vs YG8C — frequently asked

Is C2 stronger than YG8C?

Yes. C2 has a typical tensile strength of 1,200 MPa (174 ksi) against 1,100 MPa (160 ksi) for YG8C — about 9% more.

Which is cheaper, C2 or YG8C?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose C2 over YG8C?

Pick C2 when strength drives the design, or when surface hardness matters.
