Stainless Steel 1.4011 N+T vs 1.4011-QT700
Stainless Steel · 1.4011 temper comparison
1.4011 N+T and 1.4011-QT700 are two conditions of the same stainless steel grade, 1.4011: N+T (normalized and tempered) versus QT700 (hardened and tempered 675–730 °C). The chemistry is identical, so every difference below comes from the condition. 1.4011 N+T is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 480 MPa (69.6 ksi) for 1.4011-QT700, about 15% more; tensile strength follows at 760 MPa (110 ksi) vs 690 MPa (100 ksi). In exchange, 1.4011-QT700 is the more ductile: elongation 26% versus 22% for 1.4011 N+T, and 1.4011 N+T is harder (225 HB vs 200 HB).

1.4011 N+T vs 1.4011-QT700: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

1.4011 N+T vs 1.4011-QT700 — frequently asked
Is 1.4011 N+T stronger than 1.4011-QT700?
Yes. 1.4011 N+T has a typical yield strength of 550 MPa (79.8 ksi) against 480 MPa (69.6 ksi) for 1.4011-QT700 — about 15% more. Tensile strength is 760 MPa (110 ksi) vs 690 MPa (100 ksi).
Which condition does FabDigit quote by default, N+T or QT700?
N+T is the default 1.4011 condition in the FabDigit quote flow. 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, 1.4011 N+T or 1.4011-QT700?
1.4011-QT700, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 1.4011 N+T; for welding the order is 1.4011-QT700 first (fair, 45/100) then 1.4011 N+T (fair, 40/100).
