Steel A182 F11 Cl.2 N+T+SR vs A182 F11 Cl.2 Q+T
Steel · A182 F11 Cl.2 temper comparison
A182 F11 Cl.2 N+T+SR and A182 F11 Cl.2 Q+T are two conditions of the same steel grade, A182 F11 Cl.2: N+T+SR (N+T + simulated PWHT / stress relieved) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A182 F11 Cl.2 Q+T is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 320 MPa (46.4 ksi) for A182 F11 Cl.2 N+T+SR, about 41% more; tensile strength follows at 610 MPa (88.5 ksi) vs 515 MPa (74.7 ksi). In exchange, A182 F11 Cl.2 N+T+SR is the more ductile: elongation 28% versus 23% for A182 F11 Cl.2 Q+T, and A182 F11 Cl.2 Q+T is harder (187 HB vs 152 HB).

A182 F11 Cl.2 N+T+SR vs A182 F11 Cl.2 Q+T: 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.

A182 F11 Cl.2 N+T+SR vs A182 F11 Cl.2 Q+T — frequently asked
Is A182 F11 Cl.2 Q+T stronger than A182 F11 Cl.2 N+T+SR?
Yes. A182 F11 Cl.2 Q+T has a typical yield strength of 450 MPa (65.3 ksi) against 320 MPa (46.4 ksi) for A182 F11 Cl.2 N+T+SR — about 41% more. Tensile strength is 610 MPa (88.5 ksi) vs 515 MPa (74.7 ksi).
Which condition does FabDigit quote by default, N+T+SR or Q+T?
N+T is the default A182 F11 Cl.2 condition in the FabDigit quote flow (neither N+T+SR nor Q+T). 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, A182 F11 Cl.2 N+T+SR or A182 F11 Cl.2 Q+T?
A182 F11 Cl.2 N+T+SR. Its machinability rates good (58/100) against fair (50/100) for A182 F11 Cl.2 Q+T; for welding the order is A182 F11 Cl.2 N+T+SR first (good, 60/100) then A182 F11 Cl.2 Q+T (good, 55/100).
