Steel A217 WC6-A vs A217 WC6 N+T
Steel · A217 WC6 temper comparison
A217 WC6-A and A217 WC6 N+T are two conditions of the same steel grade, A217 WC6: A (solution annealed) versus N+T (normalized and tempered). The chemistry is identical, so every difference below comes from the condition. A217 WC6 N+T is the stronger of the two: yield strength 345 MPa (50 ksi) against 265 MPa (38.4 ksi) for A217 WC6-A, about 30% more; tensile strength follows at 550 MPa (79.8 ksi) vs 480 MPa (69.6 ksi). In exchange, A217 WC6-A is the more ductile: elongation 28% versus 24% for A217 WC6 N+T, and A217 WC6 N+T is harder (170 HB vs 140 HB). A217 WC6 N+T runs hotter in service (540°C vs 450°C continuous).
A217 WC6-AChoose it when the part is bent, formed or impact-loaded.
A217 WC6 N+TChoose it when strength drives the design, or when the part sees heat.
A217 WC6-A vs A217 WC6 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.

A217 WC6-A vs A217 WC6 N+T — frequently asked
Is A217 WC6 N+T stronger than A217 WC6-A?
Yes. A217 WC6 N+T has a typical yield strength of 345 MPa (50 ksi) against 265 MPa (38.4 ksi) for A217 WC6-A — about 30% more. Tensile strength is 550 MPa (79.8 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, A or N+T?
N+T is the default A217 WC6 condition in the FabDigit quote flow. 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 WC6-A or A217 WC6 N+T?
A217 WC6-A, by a small margin. Both rate good for machinability — 62/100 against 55/100 for A217 WC6 N+T; for welding the order is A217 WC6-A first (good, 65/100) then A217 WC6 N+T (good, 60/100).
