Steel P265GH Annealed vs P265GH-HR
Steel · P265GH temper comparison
P265GH Annealed and P265GH-HR are two conditions of the same steel grade, P265GH: Annealed versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. P265GH-HR is the stronger of the two: yield strength 295 MPa (42.8 ksi) against 275 MPa (39.9 ksi) for P265GH Annealed, about 7% more; tensile strength follows at 465 MPa (67.4 ksi) vs 430 MPa (62.4 ksi). In exchange, P265GH Annealed is the more ductile: elongation 32% versus 26% for P265GH-HR, and P265GH-HR is harder (140 HB vs 120 HB).
P265GH AnnealedChoose it when the part is bent, formed or impact-loaded.
P265GH-HRChoose it when strength drives the design.
P265GH Annealed vs P265GH-HR: 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.
