Steel 1035 Annealed vs 1035-CR

Steel · 1035 temper comparison

1035 Annealed and 1035-CR are two conditions of the same steel grade, 1035: Annealed versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 1035-CR is the stronger of the two: yield strength 430 MPa (62.4 ksi) against 270 MPa (39.2 ksi) for 1035 Annealed, about 59% more; tensile strength follows at 530 MPa (76.9 ksi) vs 500 MPa (72.5 ksi). In exchange, 1035 Annealed is the more ductile: elongation 30% versus 11% for 1035-CR, and 1035-CR is harder (155 HB vs 143 HB). 1035 Annealed runs hotter in service (425°C vs 300°C continuous).

1035 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

1035-CRChoose it when strength drives the design.

1035 Annealed vs 1035-CR — frequently asked

Is 1035-CR stronger than 1035 Annealed?

Yes. 1035-CR has a typical yield strength of 430 MPa (62.4 ksi) against 270 MPa (39.2 ksi) for 1035 Annealed — about 59% more. Tensile strength is 530 MPa (76.9 ksi) vs 500 MPa (72.5 ksi).

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

HR is the default 1035 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.

When should I choose 1035 Annealed over 1035-CR?

Pick 1035 Annealed when the part is bent, formed or impact-loaded, or when the part sees heat. Pick 1035-CR when strength drives the design.
