YG8 MG vs YG8 N

Ceramic · YG8 temper comparison

YG8 MG and YG8 N are two conditions of the same ceramic grade, YG8: MG (medium grain (1.5–3 µm WC), standard YG8, sinter-HIP) 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 1,200 MPa (174 ksi) for YG8 MG, about 25% more. YG8 N is harder — 1,550 HV against 1,350 HV for YG8 MG — which matters for wear surfaces and threads.

YG8 NChoose it when strength drives the design, or when surface hardness matters.
