Steel P265GH-CD vs P265GH Q&T
Steel · P265GH temper comparison
P265GH-CD and P265GH Q&T are two conditions of the same steel grade, P265GH: CD (cold drawn) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. P265GH-CD is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 340 MPa (49.3 ksi) for P265GH Q&T, about 32% more; tensile strength follows at 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi). In exchange, P265GH Q&T is the more ductile: elongation 26% versus 12% for P265GH-CD, and P265GH-CD is harder (175 HB vs 150 HB). On the shop floor, P265GH-CD machines more easily (very good vs good).
P265GH-CDChoose it when strength drives the design, or when the part is machined in volume.
P265GH Q&TChoose it when the part is bent, formed or impact-loaded.
P265GH-CD vs P265GH Q&T: 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-CD vs P265GH Q&T — frequently asked
Is P265GH-CD stronger than P265GH Q&T?
Yes. P265GH-CD has a typical yield strength of 450 MPa (65.3 ksi) against 340 MPa (49.3 ksi) for P265GH Q&T — about 32% more. Tensile strength is 560 MPa (81.2 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, CD or Q&T?
HR is the default P265GH condition in the FabDigit quote flow (neither CD nor Q&T). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, P265GH-CD or P265GH Q&T?
P265GH-CD. Its machinability rates very good (75/100) against good (63/100) for P265GH Q&T.
