Steel S460N Annealed vs S460N +N t16-40
Steel · S460N temper comparison
S460N Annealed and S460N +N t16-40 are two conditions of the same steel grade, S460N: Annealed versus +N t16-40 (+N). The chemistry is identical, so every difference below comes from the condition. S460N +N t16-40 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 320 MPa (46.4 ksi) for S460N Annealed, about 47% more; tensile strength follows at 595 MPa (86.3 ksi) vs 500 MPa (72.5 ksi). In exchange, S460N Annealed is the more ductile: elongation 28% versus 22% for S460N +N t16-40, and S460N +N t16-40 is harder (178 HB vs 150 HB).

S460N Annealed vs S460N +N t16-40: 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.

S460N Annealed vs S460N +N t16-40 — frequently asked
Is S460N +N t16-40 stronger than S460N Annealed?
Yes. S460N +N t16-40 has a typical yield strength of 470 MPa (68.2 ksi) against 320 MPa (46.4 ksi) for S460N Annealed — about 47% more. Tensile strength is 595 MPa (86.3 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, Annealed or +N t16-40?
+N is the default S460N condition in the FabDigit quote flow (neither Annealed nor +N t16-40). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, S460N Annealed or S460N +N t16-40?
S460N Annealed, by a small margin. Both rate good for machinability — 62/100 against 56/100 for S460N +N t16-40.
