Steel A216 WCC-A vs A216 WCC Q+T
Steel · A216 WCC temper comparison
A216 WCC-A and A216 WCC Q+T are two conditions of the same steel grade, A216 WCC: A (solution annealed) versus Q+T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. A216 WCC Q+T is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 290 MPa (42.1 ksi) for A216 WCC-A, about 31% more; tensile strength follows at 585 MPa (84.8 ksi) vs 500 MPa (72.5 ksi). In exchange, A216 WCC-A is the more ductile: elongation 28% versus 24% for A216 WCC Q+T, and A216 WCC Q+T is harder (190 HB vs 150 HB). On the shop floor, A216 WCC-A machines more easily (68 vs 55 out of 100).
A216 WCC-AChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
A216 WCC Q+TChoose it when strength drives the design.
A216 WCC-A vs A216 WCC 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.

A216 WCC-A vs A216 WCC Q+T — frequently asked
Is A216 WCC Q+T stronger than A216 WCC-A?
Yes. A216 WCC Q+T has a typical yield strength of 380 MPa (55.1 ksi) against 290 MPa (42.1 ksi) for A216 WCC-A — about 31% more. Tensile strength is 585 MPa (84.8 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, A or Q+T?
N+T is the default A216 WCC 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, A216 WCC-A or A216 WCC Q+T?
A216 WCC-A, by a small margin. Both rate good for machinability — 68/100 against 55/100 for A216 WCC Q+T.
