Steel P2-ANN vs P2-N

Steel · P2 temper comparison

P2-ANN and P2-N are two conditions of the same steel grade, P2: ANN (annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. P2-N is the stronger of the two: yield strength 400 MPa (58 ksi) against 330 MPa (47.9 ksi) for P2-ANN, about 21% more; tensile strength follows at 600 MPa (87 ksi) vs 510 MPa (74 ksi). In exchange, P2-ANN is the more ductile: elongation 27% versus 22% for P2-N, and P2-N is harder (150 HB vs 110 HB).

P2-ANNChoose it when the part is bent, formed or impact-loaded.

P2-NChoose it when strength drives the design.

P2-ANN vs P2-N — frequently asked

Is P2-N stronger than P2-ANN?

Yes. P2-N has a typical yield strength of 400 MPa (58 ksi) against 330 MPa (47.9 ksi) for P2-ANN — about 21% more. Tensile strength is 600 MPa (87 ksi) vs 510 MPa (74 ksi).

Which condition does FabDigit quote by default, ANN or N?

ANN is the default P2 condition in the FabDigit quote flow. 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, P2-ANN or P2-N?

P2-ANN. Its machinability rates very good (70/100) against good (65/100) for P2-N.
