Steel 50CrVA-A vs 50CrVA-CD

Steel · 50CrVA temper comparison

50CrVA-A and 50CrVA-CD are two conditions of the same steel grade, 50CrVA: A (solution annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 50CrVA-CD is the stronger of the two: yield strength 720 MPa (104 ksi) against 500 MPa (72.5 ksi) for 50CrVA-A, about 44% more; tensile strength follows at 900 MPa (131 ksi) vs 780 MPa (113 ksi). In exchange, 50CrVA-A is the more ductile: elongation 20% versus 9% for 50CrVA-CD, and 50CrVA-CD is harder (265 HB vs 225 HB).

50CrVA-AChoose it when the part is bent, formed or impact-loaded.

50CrVA-CDChoose it when strength drives the design.

50CrVA-A vs 50CrVA-CD — frequently asked

Is 50CrVA-CD stronger than 50CrVA-A?

Yes. 50CrVA-CD has a typical yield strength of 720 MPa (104 ksi) against 500 MPa (72.5 ksi) for 50CrVA-A — about 44% more. Tensile strength is 900 MPa (131 ksi) vs 780 MPa (113 ksi).

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

QT is the default 50CrVA 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, 50CrVA-A or 50CrVA-CD?

50CrVA-A. Its machinability rates good (55/100) against fair (50/100) for 50CrVA-CD.
