Steel P265NL-A vs P265NL CD+N

Steel · P265NL temper comparison

P265NL-A and P265NL CD+N are two conditions of the same steel grade, P265NL: A (solution annealed) versus CD+N (cold drawn seamless tube, subsequently normalized). The chemistry is identical, so every difference below comes from the condition. P265NL CD+N is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 255 MPa (37 ksi) for P265NL-A, about 20% more; tensile strength follows at 475 MPa (68.9 ksi) vs 425 MPa (61.6 ksi). In exchange, P265NL-A is the more ductile: elongation 33% versus 27% for P265NL CD+N, and P265NL CD+N is harder (135 HB vs 118 HB).

P265NL-AChoose it when the part is bent, formed or impact-loaded.

P265NL CD+NChoose it when strength drives the design.

P265NL-A vs P265NL CD+N — frequently asked

Is P265NL CD+N stronger than P265NL-A?

Yes. P265NL CD+N has a typical yield strength of 305 MPa (44.2 ksi) against 255 MPa (37 ksi) for P265NL-A — about 20% more. Tensile strength is 475 MPa (68.9 ksi) vs 425 MPa (61.6 ksi).

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

N is the default P265NL condition in the FabDigit quote flow (neither A nor CD+N). 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.

When should I choose P265NL-A over P265NL CD+N?

Pick P265NL-A when the part is bent, formed or impact-loaded. Pick P265NL CD+N when strength drives the design.
