Steel A216 WCA vs GE200
Steel · grade comparison
Steel A216 WCA and GE200 are both steel grades. A216 WCA is the stronger of the two: yield strength 255 MPa (37 ksi) against 230 MPa (33.4 ksi) for GE200, about 11% more. A216 WCA is the more ductile: elongation 31% versus 27% for GE200.
A216 WCAChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
A216 WCA vs GE200: 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 GE200 — frequently asked
Is A216 WCA stronger than GE200?
Yes. A216 WCA has a typical yield strength of 255 MPa (37 ksi) against 230 MPa (33.4 ksi) for GE200 — about 11% more. Tensile strength is 455 MPa (66 ksi) vs 440 MPa (63.8 ksi).
Which is cheaper, A216 WCA or GE200?
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.
When should I choose A216 WCA over GE200?
Pick A216 WCA when strength drives the design, or when the part is bent, formed or impact-loaded.
