Stainless Steel 1.4011-F vs 1.4011 N+T
Stainless Steel · 1.4011 temper comparison
1.4011-F and 1.4011 N+T are two conditions of the same stainless steel grade, 1.4011: F (as fabricated) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. 1.4011-F is the stronger of the two: yield strength 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for 1.4011 N+T, about 27% more; tensile strength follows at 1,000 MPa (145 ksi) vs 760 MPa (110 ksi). In exchange, 1.4011 N+T is the more ductile: elongation 22% versus 5% for 1.4011-F, and 1.4011-F is harder (390 HB vs 225 HB). 1.4011 N+T runs hotter in service (650°C vs 300°C continuous). On the shop floor, 1.4011 N+T machines more easily (fair vs poor) and 1.4011 N+T welds better (fair vs poor).

1.4011 N+TChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4011-F vs 1.4011 N+T: 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-F vs 1.4011 N+T — frequently asked
Is 1.4011-F stronger than 1.4011 N+T?
Yes. 1.4011-F has a typical yield strength of 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for 1.4011 N+T — about 27% more. Tensile strength is 1,000 MPa (145 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, F or N+T?
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-F or 1.4011 N+T?
1.4011 N+T. Its machinability rates fair (45/100) against poor (20/100) for 1.4011-F; for welding the order is 1.4011 N+T first (fair, 40/100) then 1.4011-F (poor, 20/100).
