Steel A572 Annealed vs A572 Normalized

Steel · A572 temper comparison

A572 Annealed and A572 Normalized are two conditions of the same steel grade, A572: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. A572 Normalized is the stronger of the two: yield strength 365 MPa (52.9 ksi) against 290 MPa (42.1 ksi) for A572 Annealed, about 26% more; tensile strength follows at 490 MPa (71.1 ksi) vs 430 MPa (62.4 ksi). In exchange, A572 Annealed is the more ductile: elongation 28% versus 24% for A572 Normalized, and A572 Normalized is harder (150 HB vs 125 HB).

A572 Annealed vs A572 Normalized — frequently asked

Is A572 Normalized stronger than A572 Annealed?

Yes. A572 Normalized has a typical yield strength of 365 MPa (52.9 ksi) against 290 MPa (42.1 ksi) for A572 Annealed — about 26% more. Tensile strength is 490 MPa (71.1 ksi) vs 430 MPa (62.4 ksi).

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

HR is the default A572 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, A572 Annealed or A572 Normalized?

A572 Annealed, by a small margin. Both rate good for machinability — 62/100 against 55/100 for A572 Normalized.
