Steel P265GH vs P92
Steel · grade comparison
Steel P265GH and P92 are both steel grades, both pressure vessel steel. P92 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 295 MPa (42.8 ksi) for P265GH, about 110% more; tensile strength follows at 850 MPa (123 ksi) vs 465 MPa (67.4 ksi). In exchange, P265GH is the more ductile: elongation 26% versus 17% for P92, and P92 is harder (280 HB vs 140 HB). P265GH conducts heat better (50 W/m·K vs 27 W/m·K). On the shop floor, P265GH machines more easily (good vs poor) and P265GH welds better (excellent vs poor).
P265GHChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
P92Choose it when strength drives the design.
P265GH vs P92: 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.

P265GH vs P92 — frequently asked
Is P92 stronger than P265GH?
Yes. P92 has a typical yield strength of 620 MPa (89.9 ksi) against 295 MPa (42.8 ksi) for P265GH — about 110% more. Tensile strength is 850 MPa (123 ksi) vs 465 MPa (67.4 ksi).
Which is cheaper, P265GH or P92?
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, P265GH or P92?
P265GH. Its machinability rates good (66/100) against poor (28/100) for P92; for welding the order is P265GH first (excellent, 90/100) then P92 (poor, 30/100).
