Steel A217 WC1-A vs A217 WC1 Q+T
Steel · A217 WC1 temper comparison
A217 WC1-A and A217 WC1 Q+T are two conditions of the same steel grade, A217 WC1: A (solution annealed) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A217 WC1 Q+T is the stronger of the two: yield strength 345 MPa (50 ksi) against 265 MPa (38.4 ksi) for A217 WC1-A, about 30% more; tensile strength follows at 545 MPa (79 ksi) vs 470 MPa (68.2 ksi). In exchange, A217 WC1-A is the more ductile: elongation 31% versus 27% for A217 WC1 Q+T, and A217 WC1 Q+T is harder (165 HB vs 140 HB).
A217 WC1-AChoose it when the part is bent, formed or impact-loaded.
A217 WC1 Q+TChoose it when strength drives the design.
A217 WC1-A vs A217 WC1 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.

A217 WC1-A vs A217 WC1 Q+T — frequently asked
Is A217 WC1 Q+T stronger than A217 WC1-A?
Yes. A217 WC1 Q+T has a typical yield strength of 345 MPa (50 ksi) against 265 MPa (38.4 ksi) for A217 WC1-A — about 30% more. Tensile strength is 545 MPa (79 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, A or Q+T?
N+T is the default A217 WC1 condition in the FabDigit quote flow (neither A 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, A217 WC1-A or A217 WC1 Q+T?
A217 WC1-A. Its machinability rates good (62/100) against fair (54/100) for A217 WC1 Q+T.
