Steel CPM S30V vs Vanadis 4 Extra
Steel · grade comparison
Steel CPM S30V and Vanadis 4 Extra are both steel grades. Vanadis 4 Extra is the stronger of the two: yield strength 1,900 MPa (276 ksi) against 700 MPa (102 ksi) for CPM S30V, about 171% more; tensile strength follows at 2,050 MPa (297 ksi) vs 950 MPa (138 ksi). In exchange, CPM S30V is the more ductile: elongation 8% versus 1% for Vanadis 4 Extra, and Vanadis 4 Extra is harder (60 HRC vs 23 HRC). CPM S30V is lighter (7.44 g/cm³ vs 7.7 g/cm³ for Vanadis 4 Extra) and Vanadis 4 Extra runs hotter in service (450°C vs 400°C continuous). On the shop floor, CPM S30V sits in a lower cost tier (premium, $$$) than Vanadis 4 Extra (high, $$$$).

Vanadis 4 ExtraChoose it when strength drives the design, or when the part sees heat.
CPM S30V vs Vanadis 4 Extra: 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.
