Steel ZG230-450-F vs ZG230-450-N

Steel · ZG230-450 temper comparison

ZG230-450-F and ZG230-450-N are two conditions of the same steel grade, ZG230-450: F (as fabricated) versus N (normalized). The chemistry is identical, so every difference below comes from the condition. ZG230-450-N is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 235 MPa (34.1 ksi) for ZG230-450-F, about 6% more. ZG230-450-N is the more ductile: elongation 23% versus 18% for ZG230-450-F.

ZG230-450-F vs ZG230-450-N — frequently asked

Is ZG230-450-N stronger than ZG230-450-F?

Yes. ZG230-450-N has a typical yield strength of 250 MPa (36.3 ksi) against 235 MPa (34.1 ksi) for ZG230-450-F — about 6% more. Tensile strength is 475 MPa (68.9 ksi) vs 460 MPa (66.7 ksi).

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

NT is the default ZG230-450 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.

Which is easier to machine, ZG230-450-F or ZG230-450-N?

ZG230-450-N. Its machinability rates good (58/100) against fair (52/100) for ZG230-450-F; for welding the order is ZG230-450-N first (very good, 79/100) then ZG230-450-F (very good, 74/100).
