Steel 5CrNiMo vs H14
Steel · grade comparison
Steel 5CrNiMo and H14 are both steel grades. Both yield at about 450 MPa — strength does not separate them. H14 is the more ductile: elongation 20% versus 18% for 5CrNiMo. H14 runs hotter in service (480°C vs 300°C continuous) and 5CrNiMo conducts heat better (33 W/m·K vs 27 W/m·K). On the shop floor, 5CrNiMo machines more easily (good vs fair) and 5CrNiMo sits in a lower cost tier (standard, $$) than H14 (premium, $$$).
5CrNiMoChoose it when the part is machined in volume, or when cost is the deciding factor.
H14Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
5CrNiMo vs H14: 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.
