Steel A217 WC6-A vs A217 WC6 N+T+PWHT
Steel · A217 WC6 temper comparison
A217 WC6-A and A217 WC6 N+T+PWHT are two conditions of the same steel grade, A217 WC6: A (solution annealed) versus N+T+PWHT (N+T + simulated post-weld heat treatment). The chemistry is identical, so every difference below comes from the condition. A217 WC6 N+T+PWHT is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 265 MPa (38.4 ksi) for A217 WC6-A, about 21% more; tensile strength follows at 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi). A217 WC6 N+T+PWHT is harder — 160 HB against 140 HB for A217 WC6-A — which matters for wear surfaces and threads. A217 WC6 N+T+PWHT runs hotter in service (540°C vs 450°C continuous).
A217 WC6 N+T+PWHTChoose it when strength drives the design, or when surface hardness matters.
A217 WC6-A vs A217 WC6 N+T+PWHT: 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.

A217 WC6-A vs A217 WC6 N+T+PWHT — frequently asked
Is A217 WC6 N+T+PWHT stronger than A217 WC6-A?
Yes. A217 WC6 N+T+PWHT has a typical yield strength of 320 MPa (46.4 ksi) against 265 MPa (38.4 ksi) for A217 WC6-A — about 21% more. Tensile strength is 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, A or N+T+PWHT?
N+T is the default A217 WC6 condition in the FabDigit quote flow (neither A nor N+T+PWHT). 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.
When should I choose A217 WC6-A over A217 WC6 N+T+PWHT?
Pick A217 WC6 N+T+PWHT when strength drives the design, or when surface hardness matters.
