Steel A266 vs P265GH
Steel · grade comparison
Steel A266 and P265GH are both steel grades. A266 is the stronger of the two: tensile strength 550 MPa (79.8 ksi) against 465 MPa (67.4 ksi) for P265GH, about 18% more. A266 is harder — 160 HB against 140 HB for P265GH — which matters for wear surfaces and threads. P265GH is stiffer (211 GPa vs 200 GPa). On the shop floor, P265GH forms better (very good vs good) and A266 sits in a lower cost tier (budget, $) than P265GH (standard, $$).
A266Choose it when strength drives the design, or when surface hardness matters.
A266 vs P265GH: 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.
