Steel A216 WCC vs G17Mn5
Steel · grade comparison
Steel A216 WCC and G17Mn5 are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 280 MPa (40.6 ksi) for G17Mn5, about 13% more. In exchange, G17Mn5 is the more ductile: elongation 28% versus 25% for A216 WCC, and A216 WCC is harder (170 HB vs 155 HB).
A216 WCCChoose it when strength drives the design.
G17Mn5Choose it when the part is bent, formed or impact-loaded.
A216 WCC vs G17Mn5: 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 G17Mn5 — frequently asked
Is A216 WCC stronger than G17Mn5?
Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 280 MPa (40.6 ksi) for G17Mn5 — about 13% more. Tensile strength is 520 MPa (75.4 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, A216 WCC or G17Mn5?
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 G17Mn5?
Pick A216 WCC when strength drives the design. Pick G17Mn5 when the part is bent, formed or impact-loaded.
