Steel A352 Grade LC1 N+T vs A352 Grade LC1 Q+T
Steel · A352 Grade LC1 temper comparison
A352 Grade LC1 N+T and A352 Grade LC1 Q+T are two conditions of the same steel grade, A352 Grade LC1: N+T (normalized and tempered) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A352 Grade LC1 Q+T is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 285 MPa (41.3 ksi) for A352 Grade LC1 N+T, about 16% more; tensile strength follows at 540 MPa (78.3 ksi) vs 500 MPa (72.5 ksi). A352 Grade LC1 Q+T is harder — 165 HB against 150 HB for A352 Grade LC1 N+T — which matters for wear surfaces and threads.
A352 Grade LC1 Q+TChoose it when strength drives the design, or when surface hardness matters.
A352 Grade LC1 N+T vs A352 Grade LC1 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.
