Steel 1005-A vs 1005-N

Steel · 1005 temper comparison

1005-A and 1005-N are two conditions of the same steel grade, 1005: A (solution annealed) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. 1005-N is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 170 MPa (24.7 ksi) for 1005-A, about 12% more; tensile strength follows at 310 MPa (45 ksi) vs 285 MPa (41.3 ksi). 1005-N is harder — 90 HB against 85 HB for 1005-A — which matters for wear surfaces and threads.

1005-NChoose it when strength drives the design, or when surface hardness matters.

1005-A vs 1005-N — frequently asked

Is 1005-N stronger than 1005-A?

Yes. 1005-N has a typical yield strength of 190 MPa (27.6 ksi) against 170 MPa (24.7 ksi) for 1005-A — about 12% more. Tensile strength is 310 MPa (45 ksi) vs 285 MPa (41.3 ksi).

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

CD is the default 1005 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.

When should I choose 1005-A over 1005-N?

Pick 1005-N when strength drives the design, or when surface hardness matters.
