Steel A352 LCC N+T-PWHT vs A352 LCC Q+T
Steel · A352 LCC temper comparison
A352 LCC N+T-PWHT and A352 LCC Q+T are two conditions of the same steel grade, A352 LCC: N+T-PWHT versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A352 LCC Q+T is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 300 MPa (43.5 ksi) for A352 LCC N+T-PWHT, about 20% more; tensile strength follows at 560 MPa (81.2 ksi) vs 510 MPa (74 ksi). A352 LCC Q+T is harder — 170 HB against 150 HB for A352 LCC N+T-PWHT — which matters for wear surfaces and threads.
A352 LCC Q+TChoose it when strength drives the design, or when surface hardness matters.
A352 LCC N+T-PWHT vs A352 LCC 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.

A352 LCC N+T-PWHT vs A352 LCC Q+T — frequently asked
Is A352 LCC Q+T stronger than A352 LCC N+T-PWHT?
Yes. A352 LCC Q+T has a typical yield strength of 360 MPa (52.2 ksi) against 300 MPa (43.5 ksi) for A352 LCC N+T-PWHT — about 20% more. Tensile strength is 560 MPa (81.2 ksi) vs 510 MPa (74 ksi).
Which condition does FabDigit quote by default, N+T-PWHT or Q+T?
N+T is the default A352 LCC condition in the FabDigit quote flow (neither N+T-PWHT 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, A352 LCC N+T-PWHT or A352 LCC Q+T?
A352 LCC N+T-PWHT, by a small margin. Both rate good for machinability — 64/100 against 58/100 for A352 LCC Q+T.
