Steel 9254 Normalized vs 9254 Q&T

Steel · 9254 temper comparison

9254 Normalized and 9254 Q&T are two conditions of the same steel grade, 9254: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 9254 Q&T is the stronger of the two: yield strength 1,700 MPa (247 ksi) against 660 MPa (95.7 ksi) for 9254 Normalized, about 158% more; tensile strength follows at 1,950 MPa (283 ksi) vs 1,030 MPa (149 ksi). In exchange, 9254 Normalized is the more ductile: elongation 14% versus 7% for 9254 Q&T, and 9254 Q&T is harder (500 HB vs 300 HB). On the shop floor, 9254 Normalized machines more easily (fair vs poor) and 9254 Normalized welds better (poor vs not recommended).

9254 Normalized vs 9254 Q&T — frequently asked

Is 9254 Q&T stronger than 9254 Normalized?

Yes. 9254 Q&T has a typical yield strength of 1,700 MPa (247 ksi) against 660 MPa (95.7 ksi) for 9254 Normalized — about 158% more. Tensile strength is 1,950 MPa (283 ksi) vs 1,030 MPa (149 ksi).

Which condition does FabDigit quote by default, Normalized or Q&T?

HR is the default 9254 condition in the FabDigit quote flow (neither Normalized nor Q&T). 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, 9254 Normalized or 9254 Q&T?

9254 Normalized. Its machinability rates fair (36/100) against poor (15/100) for 9254 Q&T; for welding the order is 9254 Normalized first (poor, 20/100) then 9254 Q&T (not recommended, 10/100).
