Steel S460N Annealed vs S460N +N t63-80
Steel · S460N temper comparison
S460N Annealed and S460N +N t63-80 are two conditions of the same steel grade, S460N: Annealed versus +N t63-80 (+N). The chemistry is identical, so every difference below comes from the condition. S460N +N t63-80 is the stronger of the two: yield strength 440 MPa (63.8 ksi) against 320 MPa (46.4 ksi) for S460N Annealed, about 38% more; tensile strength follows at 580 MPa (84.1 ksi) vs 500 MPa (72.5 ksi). In exchange, S460N Annealed is the more ductile: elongation 28% versus 21% for S460N +N t63-80, and S460N +N t63-80 is harder (172 HB vs 150 HB).

S460N Annealed vs S460N +N t63-80: 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.
