Steel 34CrAlMo5-10 vs 41CrAlMo7-10
Steel · grade comparison
Steel 34CrAlMo5-10 and 41CrAlMo7-10 are both steel grades. 41CrAlMo7-10 is the stronger of the two: yield strength 800 MPa (116 ksi) against 720 MPa (104 ksi) for 34CrAlMo5-10, about 11% more; tensile strength follows at 1,050 MPa (152 ksi) vs 900 MPa (131 ksi). 41CrAlMo7-10 is harder — 320 HB against 280 HB for 34CrAlMo5-10 — which matters for wear surfaces and threads. On the shop floor, 34CrAlMo5-10 forms better (25 vs 15 out of 100) and 41CrAlMo7-10 sits in a lower cost tier (budget, $) than 34CrAlMo5-10 (standard, $$).
41CrAlMo7-10Choose it when strength drives the design, or when surface hardness matters.
34CrAlMo5-10 vs 41CrAlMo7-10: 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.

34CrAlMo5-10 vs 41CrAlMo7-10 — frequently asked
Is 41CrAlMo7-10 stronger than 34CrAlMo5-10?
Yes. 41CrAlMo7-10 has a typical yield strength of 800 MPa (116 ksi) against 720 MPa (104 ksi) for 34CrAlMo5-10 — about 11% more. Tensile strength is 1,050 MPa (152 ksi) vs 900 MPa (131 ksi).
Which is cheaper, 34CrAlMo5-10 or 41CrAlMo7-10?
41CrAlMo7-10 is the lower-cost material: it sits in the budget tier ($) while 34CrAlMo5-10 is standard ($$). 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, 34CrAlMo5-10 or 41CrAlMo7-10?
34CrAlMo5-10, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 41CrAlMo7-10; for welding the order is 34CrAlMo5-10 first (poor, 20/100) then 41CrAlMo7-10 (poor, 15/100).
