Steel 35L-A vs 35L-N

Steel · 35L temper comparison

35L-A and 35L-N are two conditions of the same steel grade, 35L: A (solution annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 35L-N is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 270 MPa (39.2 ksi) for 35L-A, about 11% more; tensile strength follows at 540 MPa (78.3 ksi) vs 490 MPa (71.1 ksi). In exchange, 35L-A is the more ductile: elongation 18% versus 15% for 35L-N, and 35L-N is harder (170 HB vs 148 HB).

35L-AChoose it when the part is bent, formed or impact-loaded.

35L-NChoose it when strength drives the design.

35L-A vs 35L-N — frequently asked

Is 35L-N stronger than 35L-A?

Yes. 35L-N has a typical yield strength of 300 MPa (43.5 ksi) against 270 MPa (39.2 ksi) for 35L-A — about 11% more. Tensile strength is 540 MPa (78.3 ksi) vs 490 MPa (71.1 ksi).

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

N+T is the default 35L condition in the FabDigit quote flow (neither A nor 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.

Which is easier to machine, 35L-A or 35L-N?

35L-A. Its machinability rates good (60/100) against fair (52/100) for 35L-N; for welding the order is 35L-A first (fair, 50/100) then 35L-N (fair, 43/100).
