Steel 46Cr2 +A vs 46Cr2 +N

Steel · 46Cr2 temper comparison

46Cr2 +A and 46Cr2 +N are two conditions of the same steel grade, 46Cr2: +A (annealed) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. 46Cr2 +N is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 380 MPa (55.1 ksi) for 46Cr2 +A, about 21% more; tensile strength follows at 780 MPa (113 ksi) vs 640 MPa (92.8 ksi). In exchange, 46Cr2 +A is the more ductile: elongation 21% versus 16% for 46Cr2 +N, and 46Cr2 +N is harder (230 HB vs 190 HB).

46Cr2 +AChoose it when the part is bent, formed or impact-loaded.

46Cr2 +NChoose it when strength drives the design.

46Cr2 +A vs 46Cr2 +N — frequently asked

Is 46Cr2 +N stronger than 46Cr2 +A?

Yes. 46Cr2 +N has a typical yield strength of 460 MPa (66.7 ksi) against 380 MPa (55.1 ksi) for 46Cr2 +A — about 21% more. Tensile strength is 780 MPa (113 ksi) vs 640 MPa (92.8 ksi).

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

+QT is the default 46Cr2 condition in the FabDigit quote flow (neither +A nor +N). 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, 46Cr2 +A or 46Cr2 +N?

46Cr2 +A. Its machinability rates good (58/100) against fair (52/100) for 46Cr2 +N; for welding the order is 46Cr2 +A first (fair, 45/100) then 46Cr2 +N (fair, 38/100).
