Steel P265TR1 +A vs P265TR1 +C

Steel · P265TR1 temper comparison

P265TR1 +A and P265TR1 +C are two conditions of the same steel grade, P265TR1: +A (annealed) versus +C (cold drawn). The chemistry is identical, so every difference below comes from the condition. P265TR1 +C is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 260 MPa (37.7 ksi) for P265TR1 +A, about 85% more; tensile strength follows at 570 MPa (82.7 ksi) vs 420 MPa (60.9 ksi). In exchange, P265TR1 +A is the more ductile: elongation 30% versus 8% for P265TR1 +C, and P265TR1 +C is harder (175 HB vs 115 HB).

P265TR1 +AChoose it when the part is bent, formed or impact-loaded.

P265TR1 +CChoose it when strength drives the design.

P265TR1 +A vs P265TR1 +C — frequently asked

Is P265TR1 +C stronger than P265TR1 +A?

Yes. P265TR1 +C has a typical yield strength of 480 MPa (69.6 ksi) against 260 MPa (37.7 ksi) for P265TR1 +A — about 85% more. Tensile strength is 570 MPa (82.7 ksi) vs 420 MPa (60.9 ksi).

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

AR is the default P265TR1 condition in the FabDigit quote flow (neither +A 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 welds better, P265TR1 +A or P265TR1 +C?

P265TR1 +A. Its weldability rates excellent (93/100) against excellent (85/100) for P265TR1 +C.
