Steel P460NH-N vs P460NH N-70-100
Steel · P460NH temper comparison
P460NH-N and P460NH N-70-100 are two conditions of the same steel grade, P460NH: N (normalized) versus N-70-100 (+N). The chemistry is identical, so every difference below comes from the condition. P460NH-N is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 420 MPa (60.9 ksi) for P460NH N-70-100, about 14% more. P460NH-N is harder — 190 HB against 178 HB for P460NH N-70-100 — which matters for wear surfaces and threads.
P460NH-NChoose it when strength drives the design, or when surface hardness matters.
P460NH-N vs P460NH N-70-100: 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.
