Steel 5CrMnMo vs H26
Steel · grade comparison
Steel 5CrMnMo and H26 are both steel grades. H26 is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 500 MPa (72.5 ksi) for 5CrMnMo, about 12% more; tensile strength follows at 850 MPa (123 ksi) vs 780 MPa (113 ksi). 5CrMnMo is lighter (7.8 g/cm³ vs 8.89 g/cm³ for H26) and 5CrMnMo conducts heat better (34 W/m·K vs 26 W/m·K). On the shop floor, 5CrMnMo machines more easily (good vs poor), 5CrMnMo welds better (fair vs poor), and 5CrMnMo forms better (30 vs 15 out of 100).
5CrMnMoChoose it when weight is the constraint, or when the part is machined in volume.
H26Choose it when strength drives the design.
5CrMnMo vs H26: 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 H26 — frequently asked
Is H26 stronger than 5CrMnMo?
Yes. H26 has a typical yield strength of 560 MPa (81.2 ksi) against 500 MPa (72.5 ksi) for 5CrMnMo — about 12% more. Tensile strength is 850 MPa (123 ksi) vs 780 MPa (113 ksi).
Which is cheaper, 5CrMnMo or H26?
5CrMnMo is the lower-cost material: it sits in the budget tier ($) while H26 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 H26?
5CrMnMo. Its machinability rates good (55/100) against poor (32/100) for H26; for welding the order is 5CrMnMo first (fair, 35/100) then H26 (poor, 20/100).
