Steel P265TR2 +A vs P265TR2 +AR

Steel · P265TR2 temper comparison

P265TR2 +A and P265TR2 +AR are two conditions of the same steel grade, P265TR2: +A (annealed) versus +AR (hot rolled). The chemistry is identical, so every difference below comes from the condition. P265TR2 +AR is the stronger of the two: yield strength 310 MPa (45 ksi) against 255 MPa (37 ksi) for P265TR2 +A, about 22% more; tensile strength follows at 480 MPa (69.6 ksi) vs 420 MPa (60.9 ksi). In exchange, P265TR2 +A is the more ductile: elongation 30% versus 24% for P265TR2 +AR, and P265TR2 +AR is harder (135 HB vs 115 HB).

P265TR2 +AChoose it when the part is bent, formed or impact-loaded.

P265TR2 +ARChoose it when strength drives the design.

P265TR2 +A vs P265TR2 +AR — frequently asked

Is P265TR2 +AR stronger than P265TR2 +A?

Yes. P265TR2 +AR has a typical yield strength of 310 MPa (45 ksi) against 255 MPa (37 ksi) for P265TR2 +A — about 22% more. Tensile strength is 480 MPa (69.6 ksi) vs 420 MPa (60.9 ksi).

Which condition does FabDigit quote by default, +A or +AR?

+N is the default P265TR2 condition in the FabDigit quote flow (neither +A nor +AR). 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, P265TR2 +A or P265TR2 +AR?

P265TR2 +AR, by a small margin. Both rate good for machinability — 63/100 against 58/100 for P265TR2 +A.
