Steel S275NL-N vs S275NL N-63-80
Steel · S275NL temper comparison
S275NL-N and S275NL N-63-80 are two conditions of the same steel grade, S275NL: N (normalized) versus N-63-80 (+N). The chemistry is identical, so every difference below comes from the condition. S275NL-N is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 285 MPa (41.3 ksi) for S275NL N-63-80, about 12% more.

S275NL-N vs S275NL N-63-80: 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.
