Steel 5CrMnMo vs H13
Steel · grade comparison
Steel 5CrMnMo and H13 are both steel grades. Both yield at about 500 MPa — strength does not separate them. H13 is the more ductile: elongation 25% versus 18% for 5CrMnMo, and 5CrMnMo is harder (220 HB vs 205 HB). 5CrMnMo conducts heat better (34 W/m·K vs 24.5 W/m·K). On the shop floor, 5CrMnMo machines more easily (good vs fair) and 5CrMnMo sits in a lower cost tier (budget, $) than H13 (high, $$$$).
5CrMnMoChoose it when the part is machined in volume, or when cost is the deciding factor.
H13Choose it when the part is bent, formed or impact-loaded.
5CrMnMo 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.

5CrMnMo vs H13 — frequently asked
What is the difference between 5CrMnMo and H13?
Steel 5CrMnMo and H13 are both steel grades. Both yield at about 500 MPa — strength does not separate them. H13 is the more ductile: elongation 25% versus 18% for 5CrMnMo, and 5CrMnMo is harder (220 HB vs 205 HB).
Which is cheaper, 5CrMnMo or H13?
5CrMnMo is the lower-cost material: it sits in the budget 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, 5CrMnMo or H13?
5CrMnMo. Its machinability rates good (55/100) against fair (45/100) for H13.
