Steel 52CrMoV4 +N vs 52CrMoV4 +S

Steel · 52CrMoV4 temper comparison

52CrMoV4 +N and 52CrMoV4 +S are two conditions of the same steel grade, 52CrMoV4: +N (normalized) versus +S (treated for high shearability). The chemistry is identical, so every difference below comes from the condition. 52CrMoV4 +N is the stronger of the two: yield strength 600 MPa (87 ksi) against 480 MPa (69.6 ksi) for 52CrMoV4 +S, about 25% more; tensile strength follows at 950 MPa (138 ksi) vs 800 MPa (116 ksi). In exchange, 52CrMoV4 +S is the more ductile: elongation 16% versus 14% for 52CrMoV4 +N, and 52CrMoV4 +N is harder (280 HB vs 225 HB). 52CrMoV4 +N runs hotter in service (350°C vs 300°C continuous).

52CrMoV4 +NChoose it when strength drives the design, or when the part sees heat.

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

52CrMoV4 +N vs 52CrMoV4 +S — frequently asked

Is 52CrMoV4 +N stronger than 52CrMoV4 +S?

Yes. 52CrMoV4 +N has a typical yield strength of 600 MPa (87 ksi) against 480 MPa (69.6 ksi) for 52CrMoV4 +S — about 25% more. Tensile strength is 950 MPa (138 ksi) vs 800 MPa (116 ksi).

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

+QT is the default 52CrMoV4 condition in the FabDigit quote flow (neither +N nor +S). 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 +N or 52CrMoV4 +S?

52CrMoV4 +S, by a small margin. Both rate fair for machinability — 50/100 against 44/100 for 52CrMoV4 +N.
