Steel A216 WCC vs G28Mn6
Steel · grade comparison
Steel A216 WCC and G28Mn6 are both steel grades. G28Mn6 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 315 MPa (45.7 ksi) for A216 WCC, about 8% more; tensile strength follows at 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi). In exchange, A216 WCC is the more ductile: elongation 25% versus 20% for G28Mn6, and G28Mn6 is harder (180 HB vs 170 HB). A216 WCC conducts heat better (50 W/m·K vs 44 W/m·K). On the shop floor, A216 WCC welds better (excellent vs good).
A216 WCCChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
G28Mn6Choose it when strength drives the design.
A216 WCC vs G28Mn6: 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 G28Mn6 — frequently asked
Is G28Mn6 stronger than A216 WCC?
Yes. G28Mn6 has a typical yield strength of 340 MPa (49.3 ksi) against 315 MPa (45.7 ksi) for A216 WCC — about 8% more. Tensile strength is 620 MPa (89.9 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, A216 WCC or G28Mn6?
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 WCC or G28Mn6?
A216 WCC, by a small margin. Both rate good for machinability — 60/100 against 55/100 for G28Mn6; for welding the order is A216 WCC first (excellent, 85/100) then G28Mn6 (good, 58/100).
