Steel P265GH vs P285NH
Steel · grade comparison
Steel P265GH and P285NH are both steel grades. P285NH is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 295 MPa (42.8 ksi) for P265GH, about 8% more. On the shop floor, P285NH sits in a lower cost tier (budget, $) than P265GH (standard, $$).
P285NHChoose it when strength drives the design, or when cost is the deciding factor.
P265GH vs P285NH: 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.
