Steel 52CrMoV4 +A vs 52CrMoV4 +C

Steel · 52CrMoV4 temper comparison

52CrMoV4 +A and 52CrMoV4 +C are two conditions of the same steel grade, 52CrMoV4: +A (annealed) versus +C (cold drawn). The chemistry is identical, so every difference below comes from the condition. 52CrMoV4 +C is the stronger of the two: yield strength 700 MPa (102 ksi) against 470 MPa (68.2 ksi) for 52CrMoV4 +A, about 49% more; tensile strength follows at 900 MPa (131 ksi) vs 780 MPa (113 ksi). In exchange, 52CrMoV4 +A is the more ductile: elongation 18% versus 9% for 52CrMoV4 +C, and 52CrMoV4 +C is harder (265 HB vs 210 HB). 52CrMoV4 +A runs hotter in service (400°C vs 300°C continuous).

52CrMoV4 +AChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

52CrMoV4 +CChoose it when strength drives the design.

52CrMoV4 +A vs 52CrMoV4 +C — frequently asked

Is 52CrMoV4 +C stronger than 52CrMoV4 +A?

Yes. 52CrMoV4 +C has a typical yield strength of 700 MPa (102 ksi) against 470 MPa (68.2 ksi) for 52CrMoV4 +A — about 49% more. Tensile strength is 900 MPa (131 ksi) vs 780 MPa (113 ksi).

Which condition does FabDigit quote by default, +A or +C?

+QT is the default 52CrMoV4 condition in the FabDigit quote flow (neither +A nor +C). 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, 52CrMoV4 +A or 52CrMoV4 +C?

52CrMoV4 +A. Its machinability rates good (55/100) against fair (50/100) for 52CrMoV4 +C; for welding the order is 52CrMoV4 +A first (poor, 28/100) then 52CrMoV4 +C (poor, 22/100).
