Steel P265TR2 +AR vs P265TR2 +C

Steel · P265TR2 temper comparison

P265TR2 +AR and P265TR2 +C are two conditions of the same steel grade, P265TR2: +AR (hot rolled) versus +C (cold drawn). The chemistry is identical, so every difference below comes from the condition. P265TR2 +C is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 310 MPa (45 ksi) for P265TR2 +AR, about 48% more; tensile strength follows at 560 MPa (81.2 ksi) vs 480 MPa (69.6 ksi). In exchange, P265TR2 +AR is the more ductile: elongation 24% versus 8% for P265TR2 +C, and P265TR2 +C is harder (178 HB vs 135 HB). P265TR2 +AR runs hotter in service (300°C vs 250°C continuous).

P265TR2 +AR vs P265TR2 +C — frequently asked

Is P265TR2 +C stronger than P265TR2 +AR?

Yes. P265TR2 +C has a typical yield strength of 460 MPa (66.7 ksi) against 310 MPa (45 ksi) for P265TR2 +AR — about 48% more. Tensile strength is 560 MPa (81.2 ksi) vs 480 MPa (69.6 ksi).

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

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

P265TR2 +C. Its machinability rates very good (70/100) against good (63/100) for P265TR2 +AR.
