Steel A216 WCC vs GP240GH
Steel · grade comparison
Steel A216 WCC and GP240GH are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 270 MPa (39.2 ksi) for GP240GH, about 17% more; tensile strength follows at 520 MPa (75.4 ksi) vs 490 MPa (71.1 ksi). A216 WCC is harder — 170 HB against 145 HB for GP240GH — which matters for wear surfaces and threads.
A216 WCCChoose it when strength drives the design, or when surface hardness matters.
A216 WCC vs GP240GH: 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 GP240GH — frequently asked
Is A216 WCC stronger than GP240GH?
Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 270 MPa (39.2 ksi) for GP240GH — about 17% more. Tensile strength is 520 MPa (75.4 ksi) vs 490 MPa (71.1 ksi).
Which is cheaper, A216 WCC or GP240GH?
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 WCC over GP240GH?
Pick A216 WCC when strength drives the design, or when surface hardness matters.
