Steel 5CrNiMo vs H13
Steel · grade comparison
Steel 5CrNiMo and H13 are both steel grades. H13 is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 450 MPa (65.3 ksi) for 5CrNiMo, about 16% more. H13 is the more ductile: elongation 25% versus 18% for 5CrNiMo, and 5CrNiMo is harder (220 HB vs 205 HB). H13 runs hotter in service (400°C vs 300°C continuous) and 5CrNiMo conducts heat better (33 W/m·K vs 24.5 W/m·K). On the shop floor, 5CrNiMo machines more easily (good vs fair) and 5CrNiMo sits in a lower cost tier (standard, $$) than H13 (high, $$$$).
5CrNiMoChoose it when the part is machined in volume, or when cost is the deciding factor.
H13Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
5CrNiMo vs H13: 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.

5CrNiMo vs H13 — frequently asked
Is H13 stronger than 5CrNiMo?
Yes. H13 has a typical yield strength of 520 MPa (75.4 ksi) against 450 MPa (65.3 ksi) for 5CrNiMo — about 16% more. Tensile strength is 760 MPa (110 ksi) vs 760 MPa (110 ksi).
Which is cheaper, 5CrNiMo or H13?
5CrNiMo is the lower-cost material: it sits in the standard tier ($$) while H13 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 5CrNiMo or H13?
5CrNiMo. Its machinability rates good (55/100) against fair (45/100) for H13; for welding the order is H13 first (fair, 35/100) then 5CrNiMo (poor, 30/100).
