Steel A216 WCC vs GE270
Steel · grade comparison
Steel A216 WCC and GE270 are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 295 MPa (42.8 ksi) for GE270, about 7% more. A216 WCC is the more ductile: elongation 25% versus 20% for GE270, and A216 WCC is harder (170 HB vs 155 HB).
A216 WCCChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
A216 WCC vs GE270: 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 vs GE270 — frequently asked
Is A216 WCC stronger than GE270?
Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 295 MPa (42.8 ksi) for GE270 — about 7% more. Tensile strength is 520 MPa (75.4 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, A216 WCC or GE270?
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 welds better, A216 WCC or GE270?
A216 WCC. Its weldability rates excellent (85/100) against very good (78/100) for GE270.
