Steel 10G2S1-A vs 10G2S1-CD

Steel · 10G2S1 temper comparison

10G2S1-A and 10G2S1-CD are two conditions of the same steel grade, 10G2S1: A (solution annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 10G2S1-CD is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 305 MPa (44.2 ksi) for 10G2S1-A, about 57% more; tensile strength follows at 580 MPa (84.1 ksi) vs 460 MPa (66.7 ksi). In exchange, 10G2S1-A is the more ductile: elongation 28% versus 12% for 10G2S1-CD, and 10G2S1-CD is harder (185 HB vs 143 HB).

10G2S1-AChoose it when the part is bent, formed or impact-loaded.

10G2S1-CDChoose it when strength drives the design.

10G2S1-A vs 10G2S1-CD — frequently asked

Is 10G2S1-CD stronger than 10G2S1-A?

Yes. 10G2S1-CD has a typical yield strength of 480 MPa (69.6 ksi) against 305 MPa (44.2 ksi) for 10G2S1-A — about 57% more. Tensile strength is 580 MPa (84.1 ksi) vs 460 MPa (66.7 ksi).

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

HR is the default 10G2S1 condition in the FabDigit quote flow (neither A 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, 10G2S1-A or 10G2S1-CD?

10G2S1-A, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 10G2S1-CD; for welding the order is 10G2S1-A first (very good, 80/100) then 10G2S1-CD (very good, 74/100).
