Steel 34MnB5 vs P460NL2
Steel · grade comparison
Steel 34MnB5 and P460NL2 are both steel grades. P460NL2 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 420 MPa (60.9 ksi) for 34MnB5, about 14% more. P460NL2 is the more ductile: elongation 24% versus 14% for 34MnB5. On the shop floor, P460NL2 welds better (very good vs good) and P460NL2 sits in a lower cost tier (budget, $) than 34MnB5 (standard, $$).
P460NL2Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
34MnB5 vs P460NL2: 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.
