Steel 1141 Annealed vs 1141 Normalized

Steel · 1141 temper comparison

1141 Annealed and 1141 Normalized are two conditions of the same steel grade, 1141: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1141 Normalized is the stronger of the two: yield strength 405 MPa (58.7 ksi) against 350 MPa (50.8 ksi) for 1141 Annealed, about 16% more; tensile strength follows at 706 MPa (102 ksi) vs 600 MPa (87 ksi). 1141 Normalized is harder — 201 HB against 170 HB for 1141 Annealed — which matters for wear surfaces and threads. On the shop floor, 1141 Annealed forms better (fair vs poor).

1141 Annealed vs 1141 Normalized — frequently asked

Is 1141 Normalized stronger than 1141 Annealed?

Yes. 1141 Normalized has a typical yield strength of 405 MPa (58.7 ksi) against 350 MPa (50.8 ksi) for 1141 Annealed — about 16% more. Tensile strength is 706 MPa (102 ksi) vs 600 MPa (87 ksi).

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

HR is the default 1141 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, 1141 Annealed or 1141 Normalized?

1141 Normalized, by a small margin. Both rate good for machinability — 68/100 against 63/100 for 1141 Annealed.
