Steel A216 WCA vs GS240
Steel · grade comparison
Steel A216 WCA and GS240 are both steel grades. GS240 is the stronger of the two: tensile strength 480 MPa (69.6 ksi) against 455 MPa (66 ksi) for A216 WCA, about 5% more. In exchange, A216 WCA is the more ductile: elongation 31% versus 23% for GS240, and GS240 is harder (150 HB vs 130 HB).
A216 WCAChoose it when the part is bent, formed or impact-loaded.
GS240Choose it when strength drives the design.
A216 WCA vs GS240: 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 WCA vs GS240 — frequently asked
Is GS240 stronger than A216 WCA?
Yes. GS240 has a typical tensile strength of 480 MPa (69.6 ksi) against 455 MPa (66 ksi) for A216 WCA — about 5% more.
Which is cheaper, A216 WCA or GS240?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, A216 WCA or GS240?
A216 WCA, by a small margin. Both rate good for machinability — 68/100 against 62/100 for GS240.
