YG8 C vs YG8 N

Ceramic · YG8 temper comparison

YG8 C and YG8 N are two conditions of the same ceramic grade, YG8: C (coarse grain (3–6 µm WC), YG8C, maximum toughness) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. YG8 N is the stronger of the two: tensile strength 1,500 MPa (218 ksi) against 1,300 MPa (189 ksi) for YG8 C, about 15% more. In exchange, YG8 C is the more ductile: elongation 0.15% versus 0.1% for YG8 N, and YG8 N is harder (1,550 HV vs 1,180 HV). YG8 C conducts heat better (85 W/m·K vs 68 W/m·K).

YG8 CChoose it when the part is bent, formed or impact-loaded.

YG8 NChoose it when strength drives the design.

YG8 C vs YG8 N — frequently asked

Is YG8 N stronger than YG8 C?

Yes. YG8 N has a typical tensile strength of 1,500 MPa (218 ksi) against 1,300 MPa (189 ksi) for YG8 C — about 15% more.

Which condition does FabDigit quote by default, C or N?

MG is the default YG8 condition in the FabDigit quote flow (neither C nor N). 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 YG8 C over YG8 N?

Pick YG8 C when the part is bent, formed or impact-loaded. Pick YG8 N when strength drives the design.
