Steel 34CrAlMo5-10 vs Nitralloy N
Steel · grade comparison
Steel 34CrAlMo5-10 and Nitralloy N are both steel grades. Nitralloy N is the stronger of the two: yield strength 830 MPa (120 ksi) against 720 MPa (104 ksi) for 34CrAlMo5-10, about 15% more; tensile strength follows at 1,000 MPa (145 ksi) vs 900 MPa (131 ksi). Nitralloy N is the more ductile: elongation 18% versus 14% for 34CrAlMo5-10, and Nitralloy N is harder (311 HB vs 280 HB). 34CrAlMo5-10 conducts electricity better (8 % IACS vs 5.4 % IACS). On the shop floor, 34CrAlMo5-10 sits in a lower cost tier (standard, $$) than Nitralloy N (premium, $$$).

34CrAlMo5-10 vs Nitralloy N: 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.
