Steel 1022 Annealed vs 1022 Normalized

Steel · 1022 temper comparison

1022 Annealed and 1022 Normalized are two conditions of the same steel grade, 1022: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1022 Normalized is the stronger of the two: yield strength 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for 1022 Annealed, about 13% more; tensile strength follows at 455 MPa (66 ksi) vs 415 MPa (60.2 ksi). 1022 Normalized is harder — 131 HB against 111 HB for 1022 Annealed — which matters for wear surfaces and threads.

1022 Annealed vs 1022 Normalized — frequently asked

Is 1022 Normalized stronger than 1022 Annealed?

Yes. 1022 Normalized has a typical yield strength of 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for 1022 Annealed — about 13% more. Tensile strength is 455 MPa (66 ksi) vs 415 MPa (60.2 ksi).

Which condition does FabDigit quote by default, Annealed or Normalized?

HR is the default 1022 condition in the FabDigit quote flow (neither Annealed nor Normalized). 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, 1022 Annealed or 1022 Normalized?

1022 Normalized, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 1022 Annealed.
