Steel P245GH vs P265GH
Steel · grade comparison
Steel P245GH and P265GH are both steel grades. P265GH is the stronger of the two: tensile strength 465 MPa (67.4 ksi) against 440 MPa (63.8 ksi) for P245GH, about 6% more. In exchange, P245GH is the more ductile: elongation 30% versus 26% for P265GH, and P265GH is harder (140 HB vs 130 HB). On the shop floor, P245GH sits in a lower cost tier (budget, $) than P265GH (standard, $$).
P245GHChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
P265GHChoose it when strength drives the design.
P245GH 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.

P245GH vs P265GH — frequently asked
Is P265GH stronger than P245GH?
Yes. P265GH has a typical tensile strength of 465 MPa (67.4 ksi) against 440 MPa (63.8 ksi) for P245GH — about 6% more.
Which is cheaper, P245GH or P265GH?
P245GH is the lower-cost material: it sits in the budget tier ($) while P265GH is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose P245GH over P265GH?
Pick P245GH when the part is bent, formed or impact-loaded, or when cost is the deciding factor. Pick P265GH when strength drives the design.
