Steel A217 WC1-A vs A217 WC1 N+T
Steel · A217 WC1 temper comparison
A217 WC1-A and A217 WC1 N+T are two conditions of the same steel grade, A217 WC1: A (solution annealed) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. A217 WC1 N+T is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 265 MPa (38.4 ksi) for A217 WC1-A, about 9% more; tensile strength follows at 500 MPa (72.5 ksi) vs 470 MPa (68.2 ksi). A217 WC1 N+T is harder — 150 HB against 140 HB for A217 WC1-A — which matters for wear surfaces and threads.
A217 WC1 N+TChoose it when strength drives the design, or when surface hardness matters.
A217 WC1-A vs A217 WC1 N+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.
