Steel 1522 Annealed vs 1522-CR

Steel · 1522 temper comparison

1522 Annealed and 1522-CR are two conditions of the same steel grade, 1522: Annealed versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 1522-CR is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 275 MPa (39.9 ksi) for 1522 Annealed, about 67% more; tensile strength follows at 550 MPa (79.8 ksi) vs 460 MPa (66.7 ksi). In exchange, 1522 Annealed is the more ductile: elongation 27% versus 15% for 1522-CR, and 1522-CR is harder (163 HB vs 131 HB). 1522 Annealed runs hotter in service (400°C vs 300°C continuous).

1522 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1522-CRChoose it when strength drives the design.

1522 Annealed vs 1522-CR — frequently asked

Is 1522-CR stronger than 1522 Annealed?

Yes. 1522-CR has a typical yield strength of 460 MPa (66.7 ksi) against 275 MPa (39.9 ksi) for 1522 Annealed — about 67% more. Tensile strength is 550 MPa (79.8 ksi) vs 460 MPa (66.7 ksi).

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

HR is the default 1522 condition in the FabDigit quote flow (neither Annealed nor CR). 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, 1522 Annealed or 1522-CR?

1522-CR, by a small margin. Both rate good for machinability — 62/100 against 55/100 for 1522 Annealed; for welding the order is 1522 Annealed first (very good, 78/100) then 1522-CR (very good, 72/100).
