Steel ZG30CrMnSi-F vs ZG30CrMnSi-N

Steel · ZG30CrMnSi temper comparison

ZG30CrMnSi-F and ZG30CrMnSi-N are two conditions of the same steel grade, ZG30CrMnSi: F (as fabricated) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. ZG30CrMnSi-N is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 420 MPa (60.9 ksi) for ZG30CrMnSi-F, about 24% more; tensile strength follows at 780 MPa (113 ksi) vs 700 MPa (102 ksi). ZG30CrMnSi-N is the more ductile: elongation 11% versus 8% for ZG30CrMnSi-F, and ZG30CrMnSi-N is harder (235 HB vs 215 HB). ZG30CrMnSi-N runs hotter in service (400°C vs 350°C continuous).

ZG30CrMnSi-NChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

ZG30CrMnSi-F vs ZG30CrMnSi-N — frequently asked

Is ZG30CrMnSi-N stronger than ZG30CrMnSi-F?

Yes. ZG30CrMnSi-N has a typical yield strength of 520 MPa (75.4 ksi) against 420 MPa (60.9 ksi) for ZG30CrMnSi-F — about 24% more. Tensile strength is 780 MPa (113 ksi) vs 700 MPa (102 ksi).

Which condition does FabDigit quote by default, F or N?

N+T is the default ZG30CrMnSi condition in the FabDigit quote flow (neither F 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.

When should I choose ZG30CrMnSi-F over ZG30CrMnSi-N?

Pick ZG30CrMnSi-N when strength drives the design, or when the part is bent, formed or impact-loaded.
