Steel G9Ni14 vs WC4
Steel · grade comparison
Steel G9Ni14 and WC4 are both steel grades. G9Ni14 is the stronger of the two: yield strength 400 MPa (58 ksi) against 335 MPa (48.6 ksi) for WC4, about 19% more. G9Ni14 is harder — 175 HB against 163 HB for WC4 — which matters for wear surfaces and threads. WC4 runs hotter in service (540°C vs 300°C continuous) and WC4 conducts heat better (42 W/m·K vs 32 W/m·K). On the shop floor, G9Ni14 welds better (65 vs 55 out of 100) and WC4 sits in a lower cost tier (standard, $$) than G9Ni14 (premium, $$$).
G9Ni14Choose it when strength drives the design, or when surface hardness matters.
WC4Choose it when the part sees heat, or when cost is the deciding factor.
G9Ni14 vs WC4: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel 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.
