Steel 1141 Annealed vs 1141-CD

Steel · 1141 temper comparison

1141 Annealed and 1141-CD are two conditions of the same steel grade, 1141: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1141-CD is the stronger of the two: yield strength 640 MPa (92.8 ksi) against 350 MPa (50.8 ksi) for 1141 Annealed, about 83% more; tensile strength follows at 765 MPa (111 ksi) vs 600 MPa (87 ksi). In exchange, 1141 Annealed is the more ductile: elongation 25% versus 10% for 1141-CD, and 1141-CD is harder (217 HB vs 170 HB).

1141 Annealed vs 1141-CD — frequently asked

Is 1141-CD stronger than 1141 Annealed?

Yes. 1141-CD has a typical yield strength of 640 MPa (92.8 ksi) against 350 MPa (50.8 ksi) for 1141 Annealed — about 83% more. Tensile strength is 765 MPa (111 ksi) vs 600 MPa (87 ksi).

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

HR is the default 1141 condition in the FabDigit quote flow (neither Annealed nor CD). 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-CD?

1141-CD. Its machinability rates very good (72/100) against good (63/100) for 1141 Annealed.
